Newton‘s First Law

A body continues in its state of rest or of uniform motion in a straight line unless an external force acts on it. It is based on law of inertia. Inertia is the property of a body by virtue of which is opposes any change in its state of rest or of uniform motion in a straight line.

Newton‘s Second Law
The rate of change of momentum of a body is directly
proportional to the force applied on it and change in
momentum takes place in the direction of applied force.

Newton‘s Third Law
For every action, there is an equal and opposite reaction
and both act on two interacting objects.
Rocket is propelled by the principle of Newton‘s third law
