For every action, there is an equal and opposite reaction.

Energy can neither be created nor destroyed.

A particle acted on by a force will accelerate in the direction of the force.

If a particle is moving with constant velocity, it will continue to move with constant velocity unless acted on by a force.

If a particle is at rest, it will remain at rest unless acted on by a force.

Zero acceleration requires that the velocity does not change over time

Zero acceleration requires that the object is stationary

Zero acceleration requires that the force varies over time

Zero acceleration requires that the direction varies over time
