Question

Name the type of energy (kinetic energy $K$ or potential energy $U$) possessed in the following case.

The bob of a simple pendulum at its extreme position.

• A. $K$
• B. $U$
• C. $K$ and $U$
• D. No energy

Answer 1

Answer: (B)

$U$

Here simple pendulum is at a certain height and at extreme position it will not have any velocity. Hence , kinetic energy will be zero. Whereas $U=m\times g\times h$.

As it is at certain height it has some value for $h$. Hence, it will have certain potential energy.
