Consider the pendulum. At what point is the kinetic energy the greatest?
Understand the Problem
The question is asking which point on a pendulum has the highest kinetic energy. To answer this, we need to understand the concepts of potential and kinetic energy in relation to the motion of a pendulum.
Answer
Point B
The kinetic energy is greatest at point B, which is the lowest point of the pendulum's swing.
Answer for screen readers
The kinetic energy is greatest at point B, which is the lowest point of the pendulum's swing.
More Information
The greatest kinetic energy in a pendulum occurs when the pendulum swings fastest, which is at the lowest point in its path.
Tips
A common mistake is to assume kinetic energy is highest at the release points, but it's actually zero there.
