LAW OF FALLING BODIES

1. All objects accelerate downward at the same rate: 9.8m/s2

2. Galileo performed an experiment to prove that All objects Regardless of mass fall at the same rate

3. Air resistance (the upward frictional force of air) can affect the rate of a falling object.

4. Air eventually stops falling objects from accelerating.

5. When the upward force of air Is equal to the Downward force of gravity, the object stops accelerating.

(the highest velocity reached by the falling object). 6. The falling object has a constant velocity, terminal velocity (the highest velocity reached by the falling object).

7. The amount of air resistance depends on: Size Shape Speed Density
