Newton’s Laws of Motion
1. The Law of Inertia:
“An object at rest tends to stay at rest and an object in motion tends to stay in motion”
2. The Law of Proportionality:
“The acceleration of an object is directly proportional to the net force and inversely proportional to its mass.” This can be expressed in equation form: Force = (Mass) x (Acceleration)
3. The Law of Action-Reaction:
“For every action there is an equal and opposite reaction”
