Question

Can any object have mechanical energy even if its momentum is zero? Explain.

• A. True
• B. False

Answer 1

The correct option is A True

1. The total kinetic and potential energy is known as mechanical energy.
2. Momentum is equal to $\mathrm{mv}=0,\mathrm{v}=0$ since $\mathrm{m}$ can never be zero.
3. Since kinetic energy and potential energy are combined to form mechanical energy.
4. Given that the body's momentum is zero and its velocity is also zero, it possesses kinetic energy that is equal to zero.
5. However, it could possess potential energy.
6. Therefore, even if a body has no momentum, it may still have mechanical energy.

Hence, the given statement is true.
