Introduction: To find projectile motion we use equations to find the y and x of the problem, which is the distance and the max height. The equation to find y is initial height plus (starting velocity times sin of the angle) times time – half of gravity times time squared. To find x we use the equation x = (initial velocity times cos of the angle) times t. Result: Conclusion: This experiment teaches me how to accurately measure the projectile motion of the

Unformatted text preview: balls at different angles. It also shows how to accurately recognize the appropriate forces acting on the balls and show the difference between projectile motion and free fall and the forces acting on the balls. The experiment succeeds in showing the relation of freefall and projectile motion, and that they land at the same time roughly. The percent error is small....
