How a force can change the state of motion?

Explanation

To understand how a force can change the state of motion, we can break it down into several steps:

### Step-by-Step Solution:

1. **Understanding Newton's First Law of Motion**:
- According to Newton's First Law of Motion, an object at rest stays at rest, and an object in motion continues in motion with the same speed and in the same direction unless acted upon by a net external force.

**Hint**: Remember that this law emphasizes the concept of inertia, which is the tendency of objects to resist changes in their state of motion.
