Newton’s First Law of Motion (or Law of Inertia):
Every object will continue in its state of rest or uniform motion in a straight line unless a resultant force acts on it to change its state.

Newton’s Second Law of Motion:
When a resultant force acts on an object of constant mass, the object will accelerate and move in the direction of the resultant force. The product of the mass and acceleration of the object is equal to the resultant force.

Newton’s Third Law of Motion:
For every action, there is an equal and opposite reaction, and these forces act on mutually opposite bodies.
