Horizontal Projectile Motion
Horizontal projectile motion is one of the most basic examples of classical physics. Gravity is a force that causes acceleration towards the center of the Earth at 9.81 m/s2. This causes objects that are falling to increase in speed until they reach their terminal, or maximum, velocity (or until they are stopped by another force, like hitting the ground). Horizontal motion, however, is a good example of Newtonian physics: things in motion stay in motion unless acted upon by another force. If an object is traveling horizontally, it tends to travel horizontally at the same speed until another force changes its motion.
In this experiment, you will build a ramp and use that to project a ball off the table. You'll calculate the ball's velocity to determine how far the ball will travel, allowing you to anticipate the ball's trajectory and place your target in the perfect spot.
Warning is hereby given that not all Project Ideas are appropriate for all individuals or in all circumstances. Implementation of any Science Project Idea should be undertaken only in appropriate settings and with appropriate parental or other supervision. Reading and following the safety precautions of all materials used in a project is the sole responsibility of each individual. For further information, consult your state's handbook of Science Safety.
