- The
**GRAVITY**force between your coaster and the earth pulls you down the roller coaster.

- The greater a coaster’s
**WEIGHT**the stronger the tracks must be to support it.

- You increase a coaster’s
**MASS**by adding more passengers.

- A roller coaster peak is shaped in a curve
called a
**PARABOLA**so that you will feel like you are falling freely as you go over the top of the hill.

- Roller coaster hills are shaped so that you
will feel almost
**WEIGHTLESS**as you ride over them.

- You gain enough
**MOMENTUM**falling down a roller coaster hill to keep you going all the way to the top of the next hill.

- You feel
**ACCELERATION**as you gain speed rolling down a roller coaster hill.

- You feel
**DECELERATION**as you lose speed climbing a roller coaster hill.

- As your speed increases going down a roller
coaster hill, you gain
**KINETIC ENERGY.**

- Your coaster has the most
**POTENTIAL ENERGY**when it is at the highest point.

- You feel a
**FORCE**on you back as the coaster seat pushes against you.

- Your body’s
**INERTIA**causes you to be slung forward when you stop suddenly at the end of a roller coaster ride.

- Roller coaster tracks are tilted inward to
give
**CENTRIPETAL FORCE**which pushes the coaster toward the center of the curve.

- The rubbing between coaster wheels and the
track causes a
**FRICTION**force which slows the coaster down.

- Your
**VELOCITY**increases as you roll down a roller coaster hill.

**Using the
Language**

- As you roll over a peak, you rise
off you seat and you feel

- The shape of a roller coaster
hill is called a

- As you fall down a roller coaster
hill, you

- The force of

- The

- When you are the highest above
the ground, you have the most

- When you are moving the fastest,
you have the most

- Because of your speed at the
bottom of the hill, you have enough

- An inward

- Your body has

- An empty coaster and a loaded
coaster will travel down a hill at the same speed. Therefore
we can say a coaster’s speed is not affected by its
