Law of Motion

• Sir Isaac Newton is famous for the discovery of the law of gravity and also discovered the three laws of motion.
• Law of Inertia - An objects at rest remains at rest or if it is in motion continues to be in motion with a constant speed along a straight line unless acted upon by an external force.
• Law of Acceleration - The body's _____ is proportional to the magnitude of the net force acting on it, in the same direction as the net force, and inversely proportional to the mass of the body.
• Law of Interaction - It can be state that for every reaction, there is an equal and opposite reaction. This law shows that forces always occurs in pairs.
