Question

When the pendulum shown below swings from point A to point B, what happens to its total mechanical energy (ignoring friction)? (1 point) Responses Total mechanical energy is not conserved. Total mechanical energy is not conserved. Total mechanical energy goes down. Total mechanical energy goes down. Total mechanical energy stays the same. Total mechanical energy stays the same. Total mechanical energy goes up.

Answer 1

Answer: I tried...

Total mechanical energy, in the absence of friction, is conserved in a pendulum system.

So, the correct response is:

Total mechanical energy stays the same.
