What are Newton's 3 Laws?
Newton's laws are considered to be the fundamental laws of mechanics.
The first law says that:
"An object maintains its state of rest or its uniform motion unless it is acted upon by an external unbalanced force".
We know that to move or to stop a moving body we have to apply a force. This is exactly what this law states.
The mechanics of the body is contained in the Second law of motion.
