Topic 3: Newton's Law of Motion
1st Law: Inertia
Every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
Example:
2nd Law: Force
Force equal to change in momentum (mass times velocity) per change in time.
3rd Law: Action & Reaction
Every action (force) in nature there is an equal and opposite reaction.
Elements
Normal Force, (N)
Force exerted perpendicular to a surface
Mass (kg)
Quantity of matter in the object
Weight (N)
Force exerted on the object by gravity
W=mg
