Compared to the pendulum's kinetic energy at position b , its gravitational potential energy at position a is a. half as great 2. twice as great 3. the same 4. four times as great

Where is the figure that contains the locations of where these points of the pendulum are? Anyway, I'll just provide my explanation about the energy conservation in a pendulum:

In a simple pendulum with no friction, mechanical energy is conserved. Total mechanical energy is a combination of kinetic energy and gravitational potential energy. As the pendulum swings back and forth, there is a constant exchange between kinetic energy and gravitational potential energy.

I hope my answer has come to your help. Thank you for posting your question here in .
