Question

bowling ball toward his face until it touches his nose. then he lets go of the ball. which of the following best explains why the bowling ball does not touch the teacher again as it swings? a a small amount of energy is lost due to gravity. b some kinetic energy is lost due to air resistance and friction.

Explanation:

In a real - world scenario, when the bowling ball swings, air resistance and friction act on it. These non - conservative forces cause some of the ball's kinetic energy to be dissipated as heat. As a result, the ball does not have enough energy to return to the exact same position (touching the teacher's nose) on its return swing. Gravity is a conservative force and does not cause a net loss of mechanical energy in an ideal situation without non - conservative forces.

Answer:

B. Some kinetic energy is lost due to air resistance and friction.
