Background: Sir Isaac Newton was born in 1642 and dies in 1727. He was a mathematician and physicist and one of the most important sciencetific intellects of all time. He went to school at Cambridge Universtiy in 1661 and was elected a Fellow of Trinity College in 1667 and then Lucasian Professor of Mathematics in 1669. His first scientific invention was the invention of the reflecting telescope, the basic design of all large telescopes used today. He also invented calculus, the three laws of motion, and the law of universal gravitation.

This video explains Newton's Three Laws and gives examples of each:

The video also relates Momentum to Newton's Law of Motion:
-forces cause acceleration; therefore, there's a change in velocity
-if there's a change in velocity then there's a change in momentum (momentum = mass x velocity), which means that force also affects momentum

Newton’s Three Laws

First Law of Motion An object at rest will continue to stay at rest unless an outside force acts upon it; an object in motion will stay in motion unless contacted by an outside force. This is essentially Galileo's concept of inertia, and this is often termed simply the "Law of Inertia".
Second Law of Motion F= ma is Newton's Second Law of Motion. It is the relationship between mass, acceleration, and applied force (acceleration=a, mass=m, and force=F.) To move an object (change its velocity), force is applied to it (force causes acceleration). The acceleration and force also depends on the object's mass (the more mass an object has, the more force is needed to accelerate it). Acceleration and Force are vectors and in this law the direction of the force vector is the same as the direction of the acceleration vector.
Third Law of Motion For every action there is an equal and opposite reaction
