Projectile Motion picture

I hope you recognize this photo! It is our projectile motion lab. We had to predict the distance a ball would travel only knowing the height in which the ball would fall. This proved to be a difficult task since we had to translate our information and predict where the ball would fall. In the picture above the ball has just left the ramp and is about to strike the paper. This photo graph demonstrates projectile motion since the ball is moving with both a constant horizontal velocity and an increasing vertical velocity. For this experiment we needed to find the horizontal velocity since it will remain constant. Once we discovered the horizontal velocity we needed to calculate how long it would take the ball to fall. When discovering the time we were able to calculate the balls horizontal distance. This picture shows someones prediction and the ball hitting the paper!
