उत्तर
Square of amplitude
Explanation:
Energy dissipation in a simple pendulum is analysed by plotting the square of amplitude against time. Since the energy of a pendulum is proportional to the square of its amplitude, a decrease in this graph directly shows how energy is lost over time due to air resistance and friction.
