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.
This is a very clear definition of Air Resistance, and you have provided some good examples.
