Which of the diagrams shown in Figure represents variation of total mechanical energy of a pendulum oscillating in air as function of time?
Answers (1)
The answer is the option (c)
The total mechanical energy of a pendulum decreases in a continuous manner when it undergoes oscillatory motion due to the resistance offered by the air. This leads to an exponential decrease in the total mechanical energy of the pendulum. Hence, the graph c is correct, which shows an exponential curve between energy and time.
