Question
Energy does not remain conserved in an oscillating pendulum. [True/ False]
✓
Answer
False. Explanation: Simple pendulum, mechanical energy is conserved. The kinetic energy would be $\text{KE}=\frac{1}{2}\text{mv}^2$ where m is the mass of the pendulum, and v is the speed of the pendulum. However, the total energy is constant as a function of time.
