The Physics of the Vertical Jump
Ground reaction forces during a vertical jump. Ground reaction forces are the forces that the ground exerts on a jumper during the course of a vertical jump. You're maybe asking yourself: "Isn't it the other way around? Isn't the athlete exerting forces on the ground instead of the ground on the athlete?" You are not wrong! In fact, both forces ...

What are the forces acting on a catapult?
A catapult is a launching device that allows us to experimentally observe projectile motion (see Figure 1). Once the ball is launched, the only forces acting are gravity and air resistance. Gravity accelerates the ball in the negative y direction. Air resistance accelerates the ball in the opposite direction of travel.
