Newton's Law of Motion (Law of Dynamics)

• 1st Law, Law of Inertia: In the absence of a net force, a body at rest remains at rest and a body in motion will continue in motion at constant velocity 
• 2nd Law, Law  of Acceleration: When a net force acts on a body, it will be accelerated in the direction of the force with an acceleration directly proportional to the mass. (equation of motion)
• 3rd Law, Law of Interaction: When a body exerts a force on another body, the 2nd body exerts a force on the 1st body of the same magnitude but in the opposite direction.
