Rate of change of velocity measured in m/s/s

The change in motion of an object is proportional to the net force acting on it and inversely proportional to its inertia.

A set of interacting objects (needed to adequately describe a situation or event)

Object's keep on doing what they are doing.....unless acted upon by an unbalanced force

This occurs when objects' apply fundamental forces on each other

Average rate of moving over distance measure in mi/hr or m/s

An educated guess. What you can infer or conjecture.

The amount of matter in an object. Also a measure of an object's inertia.

An object's resistance to a change in motion. Also a property of matter.

A measure of an object's interaction with another object. A push or pull.

A hypothesis verified through experiment

Has both magnitude and direction. It is usually represented by an arrow.
