Question: What is the total mechanical energy of a pendulum at its highest point? (2022)

Options:

Correct Answer: Maximum potential energy

Exam Year: 2022

Solution:

At the highest point of a pendulum\'s swing, all the mechanical energy is potential energy, and kinetic energy is zero.

What is the total mechanical energy of a pendulum at its highest point? (2022)

Step 1: Understand what mechanical energy is. Mechanical energy is the sum of potential energy and kinetic energy.
Step 2: Identify the two types of energy in a pendulum: potential energy (PE) and kinetic energy (KE).
Step 3: Recognize that at the highest point of the pendulum's swing, it is momentarily at rest.
Step 4: Since the pendulum is at rest at the highest point, its kinetic energy (KE) is zero.
Step 5: At the highest point, all the mechanical energy is converted to potential energy (PE).
Step 6: Therefore, the total mechanical energy of the pendulum at its highest point is equal to its potential energy.
