Newton’s laws of motion:
First law of motion: It states that a body at rest or in motion will remain at rest or in motion unless an external force is applied on it.
Second law of motion: It states that a body will accelerates, when a force is applied on it.
The force applied, F = ma
Where ‘F’ and ‘a’ are vectors.
Third law of motion: It states that action and reaction are equal and opposite.
For every action there is an equal and opposite reaction
