Impulse and Momentum
The physics shown in this picture of me bouncing a tennis ball with my tennis racket is impulse and momentum. "Momentum is the energy of motion. Momentum changes mass, velocity, or mass and velocity. The impulse momentum theorem causes change in momentum, while impulse causes change in momentum" (Dowell 1, 2). When my racket hits the ball, the force of my racket on the ball makes an impulse on the ball. It is this time when the force is applied that is the time within the impulse equation. This action causes a change in momentum to the ball. In this picture of me bouncing the tennis ball with my racket, the physics shown is impulse and momentum, which leads to the impulse- momentum theorem.
