Can any object have mechaincal energy even if it momentum is zero ? Exaplain.

Explanation

To determine if an object can have mechanical energy even if its momentum is zero, we need to analyze the concepts of mechanical energy, momentum, and their relationship.

### Step-by-Step Solution:

1. **Define Mechanical Energy**:
Mechanical energy is the sum of kinetic energy (KE) and potential energy (PE).
\[
\text{Mechanical Energy} = KE + PE
