Newton's laws of motion
In physics, Newton's three laws of motion are the
fundamental laws of classical mechanics. These laws describe the relationship
between an object and the forces acting on it and the motion of the object
caused by these forces. These rules are as follows.
First Law: Every object is at rest or moving at constant
speed if no external force acts on it.
Newton's Second Law of Motion : The rate of change of
momentum is proportional to the applied force and the change of momentum is in
the direction of the applied force.
Newton's third law of motion: For every action force there
is a reaction force of equal magnitude and opposite direction.
