In this experiment, you will try to drop a tennis ball on a target as you run, jog, and walk past the target. Think itÃƒÂ¢Ã¯Â¿Â½Ã¯Â¿Â½s easy? Before you begin, try to guess what will happen. Try to figure out when will be the best approach (a run, walk or jog) to release the ball in order to hit the target. Give the reasons why you think you are correct and why the approaches would not be as accurate of a drop.
Demonstrate NewtonÃƒÂ¢Ã¯Â¿Â½Ã¯Â¿Â½s first law of motion inertia: An object that is in motion continues in motion in a straight line, at a constant speed, unless a force acts upon it. If it is at rest, it continues in a state of rest unless a force changes its direction. A body that resists change in motion is called inertia.
