How roller coasters use energy interactive video

What is potential energy?

• energy in motion

• electrical energy

• usable energy

• stored energy

What is directly related to (gravitational) potential energy?

• height

• speed

As the coaster climbs the hill, the amount of Potential Energy _______.

• increases

• decreases

The statement, "energy is neither created nor destroyed" is called the law of _______.

• continuation of energy

• conservation of energy

• conduction of energy

Energy in motion is called ______.

• potential energy

• kinetic energy

• movement energy

If the coaster is traveling at its fastest speed, this is also where it will have its highest ______.

• potential energy

• kinetic energy

As the coaster goes down the hill, what happens to its gravitational potential energy?

• it goes away

• it is converted to kinetic energy

Why is the train traveling so slowly when it gets up to the top of the next hill?

• Most of the potential energy has turned into kinetic energy.

• Most of the kinetic energy has turned back into gravitational potential energy.

At the top of a hill, the train has _____ energy, while at the bottom of a hill, the train has _____ energy.

• potential, kinetic

• kinetic, potential

Why does friction slow down the roller coaster?

• it increases gravity

• it destroys kinetic energy

• it causes some energy to be converted to heat
