Newton’s first law
Every body remains in a state of rest or uniform motion unless acted upon by a external force
Newton’s second law
F=ma
The amount of acceleration of a body is proportional to the acting force and inversely proportional to the mass of the body
Newton’s third law
For every action there is an equal and opposite reaction
