Question 1

What makes roller coasters move?

Accepted Answer

Roller coasters move because of gravity and the engines that lift them up high. Once they are high up, they use gravity to zoom down tracks at fast speeds.

Question 2

Why don’t we fall off roller coasters?

Accepted Answer

We're kept safe by the seats and special harnesses that hold us in place. Plus, the tracks curve in a way to keep the coaster steady even when it goes upside down.

Question 3

Why do we feel funny in our stomachs on roller coasters?

Accepted Answer

When the roller coaster moves fast up or down, it changes the forces we feel. This can make our stomachs feel tingly, like when riding in a car over a small hill.

Question 4

What are the loops on a roller coaster called?

Accepted Answer

The loops are called loops or loop-de-loops, and they use forces to keep the coaster and riders safely upside down as they go around.

Question 5

How do roller coasters stay on the track?

Accepted Answer

Roller coasters have special wheel systems that grip the track tightly. These wheels are designed to hold onto the tracks at all times, even when upside down.

Question 6

Why does a roller coaster slow down at the end?

Accepted Answer

Roller coasters slow down at the end because of brakes on the tracks. These brakes help to safely stop the ride when it's finished.

Question 7

What is the first hill on a roller coaster called?

Accepted Answer

The first hill is called the lift hill. It helps build up energy by pulling the coaster high up so it can use gravity to speed up as it goes down.

Question 8

How safe are roller coasters?

Accepted Answer

Roller coasters are very safe because they are carefully designed and tested. Engineers make sure they work properly, and safety checks are done often.

Question 9

Why do roller coasters have hills and turns?

Accepted Answer

Hills and turns make the ride exciting by changing speed and direction. They use the force of gravity to give us the feeling of flying or dropping.

Question 10

Can small kids ride roller coasters?

Accepted Answer

Some roller coasters are made just for kids, with gentler hills and slower speeds. Bigger, faster coasters have height requirements to keep everyone safe.

Question 11

What is the force that keeps us in our seats?

Accepted Answer

The force that keeps us in our seats is called gravity, along with the harnesses and safety bars. Together, they make sure we stay safely inside the coaster.

Question 12

Why do roller coasters go in circles and loops?

Accepted Answer

Circles and loops are fun because they change the direction and keep the ride thrilling. They also show us how forces like gravity can work in different directions.

Question 13

Do roller coasters operate in the rain?

Accepted Answer

Some roller coasters can run in light rain, but many stop because it's safer. Wet tracks can be slippery, so stopping prevents accidents.

Question 14

Why do you sometimes feel heavier on a roller coaster?

Accepted Answer

You feel heavier because the coaster is pressing more on you when it goes up or quickly turns. This is called 'g-force,' and it's part of the fun!

Question 15

What happens if a roller coaster stops suddenly?

Accepted Answer

If a roller coaster stops suddenly, it's usually because of a safety check. Workers will safely help everyone off, and the ride will be checked before it goes again.

Question 16

Why do roller coasters go so high?

Accepted Answer

Roller coasters go high to build up energy and make the drops more exciting. The higher they start, the faster they can go down!

Question 17

Is it true that roller coasters are faster than cars?

Accepted Answer

Some roller coasters are super fast, just like cars, and even faster sometimes! But they might feel faster because they zoom up, down, and around quickly.

Question 18

Why do we scream on roller coasters?

Accepted Answer

We scream for fun and excitement! Screaming is a way to show we're having a thrilling time and can also help when we're a little scared.

Question 19

How do engineers test roller coasters?

Accepted Answer

Engineers test roller coasters with special dolls and computers before anyone rides them. They make sure everything works and is safe for people to enjoy.

Question 20

What is the fastest roller coaster in the world?

Accepted Answer

The fastest roller coaster in the world can go over 100 miles per hour! Roller coasters like this use powerful engines and steep drops to reach such speeds.
