What is the effect of force if the goalkeeper manage to catch the ball?

When a goalkeeper catches a ball, the force exerted by the ball is transferred to the goalkeeper's hands and arms, causing them to experience a deceleration of the ball's momentum. This action requires the goalkeeper to apply an equal and opposite force to stop the ball's motion, which is governed by Newton's third law of motion. If the catch is successful, the force is absorbed by the goalkeeper's body, minimizing the impact and allowing them to maintain control of the ball. The effectiveness of the catch also depends on the technique and strength of the goalkeeper.
