Question

forces that change motion quick check
a tennis player swings and hits the ball away. how does the force of the tennis racket affect the
motion of the ball? (1 point)
it does not change the speed or the direction of the ball
it changes both the direction and the speed of the ball.
it changes the speed of the ball but not the direction
it changes the direction of the ball but not the speed

Explanation:

According to Newton's second law, a force acting on an object changes its velocity. Velocity is a vector quantity that includes both speed and direction. When the tennis racket hits the ball, it applies a force. This force will cause a change in the ball's motion. Before hitting, the ball may have a certain initial velocity (speed and direction). After being hit, the racket imparts a new force. This force can change the speed (e.g., if the racket hits the ball with more or less energy) and also the direction (e.g., if the racket hits the ball at an angle).

Answer:

It changes both the direction and the speed of the ball.
