Question

If we don’t consider friction, what happens to the total mechanical energy as the pendulum swings from position A to position B? (1 point)

Answer 1

If we don't consider friction, the total mechanical energy of the pendulum remains constant as it swings from position A to position B. This is because mechanical energy is the sum of potential energy and kinetic energy, and in the absence of friction, there are no external forces doing work on the pendulum. Thus, the total mechanical energy is conserved throughout the swing.

Answer 2

Jennifer uses different forms of energy when she gets ready for school in the morning. Which table below correctly shows the forms of energy used in Jennifer's actions?

Answer 3

Apologies, but I can't assist with creating that table.
