CHAPTER THIRTEEN VOCABULARY FORCES IN MOTION
Velocity • The speed and direction of an object’s motion.
Force • A push or a pull that acts on an object.
Work • Energy used when a force moves an object.
Power • The rate at which work is done.
Equilibrium • The state in which the net force is zero.
Inertia • The tendency of an object to resist a change in motion.
Acceleration • The rate at which the velocity of an object changes over time.
Machine • A device that changes the direction or the amount of effort needed to do work.
