Is force needed to keep a moving body in motion ?

Explanation

To answer the question, "Is force needed to keep a moving body in motion?" we can follow these steps:

### Step 1: Understand Newton's First Law of Motion
According to Newton's First Law of Motion, an object at rest will stay at rest, and an object in motion will remain in motion with the same speed and in the same direction unless acted upon by an external force.

### Step 2: Analyze the Concept of Motion
If a body is already in motion, it does not require any force to continue moving. This is because, in the absence of external forces (like friction or air resistance), the body will continue to move indefinitely at a constant velocity.
