Question

In simple harmonic motion, loss of kinetic energy is proportional to

• A. $e^x$
• B. $x^3$
• C. $logx$
• D. $x^2$

Answer 1

Answer: (D)

$x^2$

Since the energy is conserved in an SHM, the loss in kinetic energy is equal to the gain in potential energy.

Thus, loss in kinetic energy $\propto x^2$.
