An object in motions stays in motion, an object at rest stays at rest, until acted on by an outside force

There is a relation between the size of a force, the amount of mass, and the amount the object will accelerate.

For every action (force) there is an equal and opposite action (force)

The amount of matter in an object, or the amount of inertia an object has

When all forces effecting an object cancel out. Causes no acceleration

The the forces effecting and object don't cancel out. Causes acceleration.

Any push or pull

Electrical property caused by unbalanced amounts of electrons

An objects resistance to changes in motion, a property of matter.

How fast and what direction an object is moving. Distance divided by time.

Not moving

Rate of change in speed. Units have one distance and time twice.

When two objects touch, always transfers energy.

A part of the world that you are modeling in order too understand it more simply.

Force caused by two objects rubbing. Always in the opposite direction of motion.

Data, observations, or information that supports your claim.

The information gathered during an investigation.

How likely a system is to change.

A way of describing a system to understand it better, but simpler.

Your answer or explanation for why. Needs evidence to support it.
