Marble Run Explanation

Marble Run Explanation 

At the top of the marble run, on the platform where the start is, it is potential energy acting upon the marble. This is because the marble has the potential to start moving, but the energy is stored until we let it go.

When we let the marble go down the first s-bend, it is the result of kinetic energy, because the marble is in motion. At the end of the first s-bend is a loop, and when passing through this, the marble accelerates - this is acceleration acting upon the marble.

During the windy bends,  there is friction acting upon the marble, The plastic doors help to slow the marble down, creating friction between the two objects. 

At the end of the windy bends, is a bowl, followed by a tunnel. The marble falling down the tunnel is an act of gravity, because the marble is being pulled down towards the ground. 

After the tunnel is another s-bend. During this time, kinetic energy is working upon the marble, which is in motion. 

Another bowl is at the end of this s-bend, and gravity acts upon the marble once again. 

The marble rolls down another s-bend, and through a gear mill. The gear mill works to slow the marble down, creating friction between the marble and itself. 

The marble stops, at the end platform. The marble cannot move from here, unless it is impacted by another force, such as wind, or a hand picking it up. These are balanced forces working upon the marble.

That is an explanation of the forces acting upon the marble during the marble run. 

My annotated diagram of the marble run. Here you can see the forces acting upon the marble during it's run labelled, and also how our marble run looked like.

Summary: 

The most common force working upon the marble during the marble run was kinetic energy.

The least common force (s) working upon the marble during the marble run were balanced forces, potential energy, and acceleration.

High Impact Kete #11: Motion

Motion

An object in motion is a moving object; a change in position over time. A flying bird is in motion, because they are not still, but moving. Motion impacts many things across the Earth, including yourself. When you walk, run, jog, sprint, or even just stand up or sit down, you are in motion.

The car to the right is in motion because it is moving. 

The baseball on the left is in motion because it is moving.











Some examples of motion being applied in real life include:

- A soccer ball, netball, basketball, or hockey ball rolling across the ground if you kick it, or flying through mid-air if you throw it. 

- Your lips and mouth while you are speaking.

- Your whole body if you are running, walking, sprinting or jogging for sport, P.E, or fitness.

- Your hand if you are waving hello or goodbye at someone. 

High Impact Kete #11: Unbalanced Forces

Unbalanced Forces

Unbalanced forces are forces that can cause still objects to move, or moving objects to stop, slow, accelerate or change direction. 

Above is a diagram demonstrating unbalanced forces on a truck. A smaller force is acting upon the front of the truck, and a larger force is acting upon the tail. The truck is accelerating in the direction of the small force. These two forces of unequal proportions are unbalanced. 

Some examples of unbalanced forces include:

- If you kicked a still soccer ball, you would be causing a balanced object to move, thus creating an unbalanced force.

- If you slid a book across the floor of the room, but a person kicked it out of the way, changing it's direction, you would be creating an unbalanced force to act upon the book, as you have changed the balanced forces' direction. 

- If you bounced a ball onto the ground and let it bounce back up again, but another person catches it mid air, an unbalanced force would be acting upon the ball, because they have made a balanced force stop. 

High Impact Kete #10: Acceleration

Acceleration

Acceleration is the measurement of how fast speed (velocity) changes. If an object was falling at 10 metres per second, and it speeds up to 15 metres per second, it has accelerated. 

Below is a Google Drawing of an example of acceleration. On the right side, you can see she has accelerated, as she is now walking faster than she had been before, on the left side.

Some examples of acceleration in everyday life include:

- Your pace while running during fitness, cross country, winter sports or P.E class.
- Your speed while walking to class, and walking faster if you were running late.
- The velocity of the car you are sitting in.

High Impact Kete #7: Pull

Pull

Pull is a force that motions backwards towards the origin. For example, if you were to take an apple off a table from in front of you, and took it backwards towards yourself, you would be demonstrating pull.

Above is a video I made of me pulling something. I am pulling the Starbucks cup away from where it was sitting on the desk. 

Some examples of pull being used in everyday life include:

- If you take something off your desk, table, or bench. You are pulling the object away.

- If you play tug of war. You are pulling on one side of the rope. 

High Impact Kete #9: Balanced Forces

Balanced Forces

Balanced Forces are two equals forces acting in opposing directions on one object. When the balanced force is acting upon this object, it will remain still or at the same speed or direction as it had been before, even before the balanced force. Balanced forces can act upon all hanging, floating and standing objects.

This water bottle is a balanced force sitting on a table, as it is not moving.

This tiny adorable cactus is a balanced force sitting on a table, as it is not moving. 

This hanging ornament is a balanced force, because it is not moving. If an earthquake were to happen though, or someone used some sort of force to impact its position, it would become an unbalanced force.

This pineapple decor is an unbalanced force because it is not moving. 

Some examples of balanced forces in everyday life include:

- A Chromebook sitting on a table

-  A football sitting still on a field 

- A table sitting on a floor.

High Impact Kete #8: Air Resistance

Air Resistance

Air Resistance (sometimes called drag) is a frictional force in which air pushes against a moving object. The force increases as the object moves faster. The fluid (gas, liquid or air) pushes back on the object. 

Some examples of air resistance in everyday life include:

- If you bounce a ball, and it comes back up to a certain height, it is air resistance from above acting upon the ball to make it stop bouncing higher.

- If you put your hand out of a car window while it is going fast, and your hand pushes back towards the end of the window, that is air resistance acting upon the hand to push it back. 

- Blowing something light (such as a feather or cotton ball) is air resistance acting upon the light object.

See Saws

See Saws 

1. If 2 people are of equal weight where do they need to sit on the see saw to balance it?

Answer: At an equal distance from one another.

2. If 1 person is heavier where does this person need to sit to balance?

Note: Each person's weight is a force pushing down on the see saw.

Explode/Implode

Explode/Implode

Below > Cold water: Bottle collapsed. Force acting on outside of the bottle was greater than force acting inside. 

Why? The particles inside of the bottle crowd together and stop moving, then, the pressure from the outside presses in. The result is a collapsed bottle. 

The milk carton with no water, lid on, and cooled.

The milk carton with hot water and lid on

Hot water: The forces acting out are greater than the forces acting on it. Expanded shape.

Empty milk carton, cooled, lid on.

Empty: Inside and outside forces acting on the bottle are equal. Normal shape.

High Impact Kete #6: Kinetic Energy

Kinetic Energy

Kinetic energy is the energy an objects possesses when it is in motion. The energy can be converted into lots of other things, including gravitational or electric potential energy. 

Below is a Google drawing I created of kinetic energy being demonstrated on a roller coaster. 

Some examples of kinetic energy because used include:

-The motion of a door, chromebook lid, or book cover, being opened or shut
-Yourself running during fitness
-A table when it is being moved across the room 

High Impact Kete #5: Gravity

Gravity

Gravity is one of the most important forces in our solar system. It is a natural force which pulls everything and anything to the centre of the Earth. It is the reason objects, when dropped, fall to the ground, not to the ceiling, and why we don't float. The closer two objects are to each other, the more gravity will affect them.

In space, there is no gravity, and that's why you see astronauts floating in their spaceships instead of walking on the ground. This is called an anti-gravity environment. 

It was Sir Isaac Newton that discovered gravity back in the 15th century. 

High Impact Kete #4: Push

Push

Push is a force/motion you apply to something if you want to move. For example, if you want to move an object such as an eraser across a table, to move it, you would push it.

Basically, push is the force applied to move something away from you.

A video I made displaying me pushing a tiny cactus plant thing.

Some examples of push being used in real life include:

- Shutting a Chromebook lid. You are pushing down.
- Opening a door. You push against it to open it. 
- Shutting your tote tray. You are pushing it away from you. 
- Pushing somebody out of the way. You are pushing them away from you. (not that I'd recommend that or anything)

Concordes vs. Cargo Planes

Concorde vs. Cargo Planes

The Concorde was a French-British passenger plane that flew faster than the speed of sound. It operated from 1976 to 2003;

Cargo planes are planes that carry freight or mail, although in some instances, they can carry passengers. Military cargo planes carry things such as army tank parts, troopers, and paratroopers. 

The most noticeable difference between them is the speed. The Concorde could cross the Atlantic Ocean in 3 and a half hours, but cargo and passenger planes take about 8 hours. 

Another difference is the numbers made. There were only 20 Concordes made, including 3 non-airline planes, but there are currently about 23,600 cargo planes.

There have been 80 fatal cargo plane crashes, but the Concorde only had one. In late July 2000, an Air France Concorde Plane 4590, scheduled to New York City, from Paris, France, crashed into a German hotel, shortly after take-off. The plane ran over debris on the runway, resulting in a punctured tyre and fuel tank. All 100 passengers and 9 crew members aboard the Concorde were killed. This was the only crash during it's 27-year history. 

G-Forces: What are they?

G-forces

G-force is an object's acceleration in proportion to free falling. Astronauts in space go through unusually g-forces (either low or high) in oppose to Planet Earth, where the force is 1g, or 9.8 meters per second squared.

A good example of g-forces are on roller coasters. When you go down a large drop, the g-force results in you getting pushed back in your seat. This is relative to planes, too, as you get pushed back in your seat during take off. The g-force is actually rotating at this time. 

Isaac Newton

Sir Isaac Newton

Sir Isaac Newton, born 1642 in Lincolnshire, England, was an English physicist, mathematician and astronomer.
His most popular work was the discovery of gravity, a powerful force which pulls everything on Earth into the centre; therefore keeping it intact, and is the the reason why things fall to the floor instead of float, or to the ceiling. In space, there is no gravity.
Gravity is an important force in both real life and our High Impact Kete.

Sir Isaac Newton.

In 1687 (the 15th century) Newton established a set of three laws of motion, today they are widely known as 'Newton's Laws'. They are a study of both dynamics and motions.
These three laws revolve around acceleration, gravity, pressure, and other forces such as those. 

The first law: 
If an object is moving, it will move in a straight line unless affected at an angle by some force; such as wind or gravity.


The second law:

The acceleration of an object is the increase of velocity in the same direction as the force acting upon it.

The third law:

The force you apply to the object is the same force applied to your hands as you do so.

High Impact Kete #3: Potential Energy

Potential Energy

Potential Energy is the stored energy has as a result of its position, angle, or state. 

If a car is moving, it is the result of kinetic energy. If a car is stopped, at a traffic light for example, it is the result of potential energy. It has the power to accelerate but is not using its ability. 

Some examples of potential energy include:

- A running car at a stop sign (it can accelerate at anytime)

- Branches on a tree (because they can fall to the ground)

- Doors and Chromebook lids (they can open and shut)

There are other kinds of potential energy, too. 

Chemical potential energy is stored in batteries when they have not been implanted into a remote, computer etc. 

Electric potential energy is stored in light bulbs and other light sources when it is switched off. 

Elastic potential energy is stored in elastic rubber bands or springs. 

Below is a Google slide I created of all the potential energy examples.

High Impact Kete #2: Friction

Friction

Friction is a force that acts to prevent the movement of two touching objects. There are two kinds of friction; static and kinetic.

Kinetic friction is when the frictional force is not strong enough to stop the touching objects moving. An example of this is sandpaper against wood.

Static friction is when the frictional force is strong enough to stop touching objects moving. An example of this is a person climbing a pole. 

Imagine you are rubbing your hands together quickly. What does it create? Heat and sound. That's the result of the friction. 

Some examples of sliding friction include sliding down a playground slide, jeans on your legs while putting them on, and the bottom of the chair leg and floor when moving the chair. 

Below is a diagram of an example of friction that I created on Google Drawings.

High Impact Kete #1: Force

Force

In the field of physics, force is the push or pull that alters and changes the direction, velocity or shape of an object. There are three laws of force, which are named Newton's Law. Below are the definitions of these laws, and are simplified in my own words.

The first law:

If an object is moving, it will move in a straight line unless affected at an angle by some force; such as wind or gravity.

_

The second law:

The acceleration of an object is the increase of velocity in the same direction as the force acting upon it. 

_

The third law:

The force you apply to the object is the same force applied to your hands as you do so.

To kick the soccer ball, the girl is applying force to it. 
As the soccer ball comes down, it is gravity pulling it. 

Term 1 Art Assessment 2017

A pencil sketch of Captain America from the very beginning; when we were first introduced to the form of comics and superheroes.

A second Flash superhero inspired pencil sketch, in a different position rather than standing.

First draft painting - small landscape, the final artwork involved many minor changes.

Painted landscape - based on Lake Ellesmere. The superhero is to be painted on. I gave this an excelled so far but I am looking to complete it in the future.

Note: There had been two other pencil sketches but they were lost; although they were mostly experimental. 

I learned lots of things from this term of art. Noticeably, my shading has improved because of the new techniques I was taught early on. I also believe my painting skill has increased; I included many new textures.
