# What is Newton's hypothesis?

###### September 01, 2007 8:45PM

Newton's hypothesis included the 3 laws of motion.

The first law states that:

Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

His 2nd law states that:

The relationship between an object's mass m, its acceleration a, and the applied force F is given by F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.

His 3rd law states that:

For every action there is an equal and opposite reaction.
