Newton’s first law of motion
If the forces acting on an object are balanced then the resultant force of an object is zero
Newton’s second law of motion
The acceleration of an object is directly proportional to the force as force=mass*acceleration
E.g the higher the resultant force the more the acceleration
Newton’s third law of motion
When two objects interact with each other they exert equal and opposite forces on each other.
