A tennis player swings and hits the bar away. How does the force of the tennis racket affect the motion of the ball?
1 answer
The force of the tennis racket on the ball affects its motion by transferring momentum to the ball. When the tennis player swings the racket, they apply a force to the ball, causing it to accelerate. As a result, the ball gains velocity in the direction of the force applied by the racket. The magnitude and direction of the force determine the speed, angle, and spin of the ball. The spin creates aerodynamic forces that affect the trajectory and bounce of the ball, making it curve or dip as it moves through the air. The force from the racket also gives the ball kinetic energy, allowing it to travel a certain distance before decelerating due to air resistance and gravity.
