Question

The diagram shows a simple pendulum. Neglecting friction, what happens to the total mechanical energy as the pendulum swings from position A to position B?Captionless ImageResponsesIt decreases.It decreases.It increases.It increases.It remains the same.It remains the same.It is not conserved.

Answer 1

The diagram is not provided, but based on the information given, the correct response would be "It remains the same". In an idealized system without friction, the total mechanical energy of a simple pendulum is conserved (i.e., it remains constant) as it swings back and forth between positions A and B.

Answer 2

its wrong

Answer 3

Apologies for the incorrect response. Without further information or a diagram, it is difficult to determine the exact behavior of the pendulum as it swings from position A to position B. However, if neglecting friction, the total mechanical energy of the pendulum should indeed remain constant.
