1. Force of Impact: This is the force the ball exerts on your hand as it makes contact. It's a sudden and strong force that needs to be absorbed.
2. Force of Resistance: This is the force your hand exerts back on the ball to slow it down and bring it to a stop. This force is applied over a short period of time to minimize the impact.
It's important to note that these forces are actually part of a single interaction – Newton's Third Law of Motion. For every action, there is an equal and opposite reaction. The ball exerts a force on your hand, and your hand exerts an equal and opposite force on the ball.
