State Newton's 3 Laws in words and/or mathematically

1st Law - An object will remain at rest or continue at constant velocity unless acted on by an unbalanced force
2nd Law - F=ma (for a constant mass body) /the net force acting on a body is directly proportional to the rate of change of momentum
3rd Law - If body A exerts a force on body B, body B will exert an equal and opposite force on body A
