Final answer:
The force of a bat on a ball and the force of a ball on a bat are equal in magnitude and opposite in direction according to Newton's third law of motion in Physics.
Step-by-step explanation:
The force of a bat on a ball and the force of a ball on a bat are equal in magnitude and opposite in direction. This is known as Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. When a bat strikes a ball, the bat exerts a force on the ball. At the same time, the ball exerts an equal and opposite force on the bat.
This interaction between the bat and the ball is what allows the ball to accelerate and change its direction. For example, when a batter hits a baseball with a bat, the force of the bat on the ball causes the ball to accelerate and move in the opposite direction. At the same time, the force of the ball on the bat causes the bat to experience a recoil or a backward force.
