Projectiles Launched at an Angle
Throwing a ball to a friend or shooting a cannon are both examples of projectile motion. Gravity is a force that acts upon objects, drawing them towards the center of the Earth at 9.81 m/s2. Horizontal motion happens when an object is acted upon by an outside force, and it will stay in motion until acted upon by another force, including hitting the ground. Newton’s Third Law of Motion says that an object will stay in motion unless acted on by an outside force, so this means that there is no acceleration in the horizontal direction.
The angle at which something is thrown or shot also affects how far it will travel, because what goes up must come down!
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.
