this measures the rate at which speed changes.  Happens when a roller coaster car is being pulled down a hill by gravity and the speed is increasing.

• speed limit
• acceleration
• motion
• inertia

energy that combines potential energy with kinetic energy.  The ability to cause motion.

• chemical energy
• kinetic energy
• potential energy
• mechanical energy

a push or a pull

• force
• tides
• a swing
• gravity

energy an object has due to its position or condition.  Stored energy.

• kinetic energy
• potential energy
• energy transfer
• mechanical energy

ability to cause motion and create change

• energy
• work

This will keep you in your seat on a roller coaster when going through a teardrop loop.  Says an object will stay traveling in the same direction unless it is changed by a force.

• friction
• force
• inertia
• seat belt

a force between 2 objects that rub together; to work against the motion of an object.  A force that will slow an object down.
