State first law of motion and explain it

Explanation:

Newton's first law:
the law of inertia Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.


Final Answer:

Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion. For example; A block kept on the table will be at rest until net external force applied to it but when external force apply it will start to move.
