Chapter 4, Problem 45R

To determine

To explain: The energy transformations.

Explanation of Solution

Introduction:

According to the law of conservation of energy, energy is not created or destroyed but is transformed from one form to a different form.

At the highest point of the swing’s path, the gravitational potential energy is the greatest and kinetic energy is least. As the swing starts moving down, gravitational potential energy decreases as kinetic energy increases. At the lowest point in the path of the swing, the kinetic energy is greatest and gravitational potential energy is least.

Conclusion:

The energy transformation in the given figure is:

Gravitational potential energy to kinetic energy.
