Is it possible exert a force which does work on a body without changing its kinetic energy? If so, give example.

Explanation

To determine if it is possible to exert a force that does work on a body without changing its kinetic energy, we can analyze the situation step by step.

### Step-by-Step Solution:

1. **Understanding Work and Kinetic Energy**:
- Work (W) is defined as the product of the force (F) applied to an object and the displacement (d) of that object in the direction of the force. Mathematically, \( W = F \cdot d \).
- Kinetic energy (KE) is given by the formula \( KE = \frac{1}{2}mv^2 \), where \( m \) is the mass of the object and \( v \) is its velocity.
