Question

When you view the pendulum’s swing, it shows that at the very top of the swing KE = 0. What does that tell you about the pendulum’s motion at that point?

Answer: Sample Response: If KE = 0, the pendulum is not moving. At the top of the swing, the pendulum must stop for a brief moment.
What you need to include:
Zero kinetic energy means the pendulum is not moving.
The pendulum stops at the top of the swing.

Answer 1

The kinetic energy of an object is given by: Kinetic energy = 1/2 * mass * velocity If the kinetic energy of the pendulum at the top of its swing is 0, then this tells us that the velocity of the pendulum at that point is 0

Answer 2

If KE = 0, the pendulum is not moving. At the top of the swing, the pendulum must stop for a brief moment.
