Newton's First Law of Motion

Newton's first law of motion is also known as the law of inertia. It states that a body will continue in its state of rest or uniform motion in a straight line unless acted upon by some external force. This means that if an object is at rest, it will stay at rest, and if it is moving at a constant speed in a straight line, it will continue to do so unless something else interferes.

Explanation

The first law of motion is based on the concept of inertia, which is the tendency of an object to resist a change in its state of motion. In other words, an object will continue to do what it is doing unless something else makes it change. This can be seen in everyday life when you try to push a stationary object, such as a heavy box. It will not move unless you apply a force to it.

Similarly, if an object is already in motion, it will keep moving in a straight line at a constant speed unless some external force acts upon it. For example, if you slide a hockey puck across the ice, it will keep moving until it hits something or is acted upon by another force, such as friction.

Conclusion

Newton's first law of motion is a fundamental concept in physics. It explains how objects behave when no external forces are acting upon them. By understanding this law, scientists and engineers can design better machines and devices, and also predict how objects will behave in various situations.

Body is in the motion it tends t
o be in motion and when a body is in the rest it tends to be in rest unless and external force is not applied on it.
