It becomes greater.
It becomes greater.

It remains the same

Answer 1

If we don’t consider friction, the total mechanical energy of the pendulum remains the same as it swings from position A to position B. This is due to the conservation of mechanical energy, where the potential energy at the highest point is converted to kinetic energy at the lowest point, and vice versa. Therefore, the correct response is:

It remains the same.
