Newton's Laws of Motion

Publication in which Sir Isaac Newton described force and how they act

Force is equal to mass times acceleration

An object acted upon by a net force will accelerate in the direction of that force

Momentum is equal to mass times velocity

The outward forces exerted by a surface

The speed an object reaches when the force of gravity is balanced by the force of air resistance.

The force neccesary to stop an 80kg bicyclist in 10 s if she's riding at 4 m/s

After a diver jumps forward from the diving board, the force of GRAVITY will accelerate her parallel to the direction of motion

If the diver doesn't have the correct form when she enters the water, the force of the water can accelerate her speed.

When the diver enters the water, the force of the water is opposite to the velocity of the diver.
