What is inertia?

• An object will stop for no reason.

• An object at rest will stay at rest. An object in motion will stay in motion.

• An object will move all by itself.

What is the difference between speed and velocity?

• Speed is how fast an object moves. Velocity is how fast an object moves AND the direction it moves in.

• Speed is the momentum. Velocity is inertia.

• Speed is the rate at which an object remains at rest. Velocity is how fast it moves and stops.
