A body of mass m moving with a velocity v is acted upon by a force. Write expression for change in momentum of the following case:
when `v lt lt c`

Explanation

To solve the problem of finding the change in momentum of a body of mass \( m \) moving with a velocity \( v \) when acted upon by a force, we can follow these steps:

### Step 1: Write the formula for momentum
The momentum \( p \) of an object is defined as the product of its mass and velocity. The formula for momentum is given by:
\[ p = m \cdot v \]
