Use the diagram below to answer the question. E
The diagram above shows the motion of a pendulum as it swings from position A to position E. Which answer choice explains
what happens to the total mechanical energy of the pendulum as it swings from position A to position E?
O A. Air resistance causes the total mechanical energy to increase at point then decrease at point E.
OB. Air resistance causes some of the pendulum's energy to convert into thermal energy resulting in a decrease of the pendulum's total
mechanical energy.
O C. Air resistance destroys some of the pendulum's total mechanical energy causing it to decrease.
D. Air resistance creates thermal energy causing the pendulum's total mechanical energy to increase
