Accepted Answer

friction between the coaster car and the track, friction between the coaster car and air resistance.

Question 2

The picture is an example of...

Accepted Answer

you will keep going in a direction, unless something happens, the Law of Inertia, Newton's First Law

Question 3

When you top a hill, what force carries you up while the car has already started down the hill?

Accepted Answer

inertia

Question 4

Potential Energy is referred to as...

Accepted Answer

stored energy

Question 5

Since a roller coaster has no engine, the coaster car is moved by gravity and momentum.

Accepted Answer

true

Question 6

If the track slopes down, gravity pulls the front of the car toward the ground...

Accepted Answer

all of the above

Question 7

Which statement fits the picture?

Accepted Answer

F = mass x acceleration, Newton's Second Law of Motion, the same force on these 2 objects = different accelerations, The movement of the smaller mass will be greater.

Question 8

What is an example of centripetal force?

Accepted Answer

cars going around a banked curved, a tornado, the hammer throw, a loop on a roller coaster

Question 9

The first American roller coaster was actually a train for moving coal down a mountain.

Accepted Answer

true

Question 10

What is it called when you go over a hill and actually lift up out of your seat for an instant?

Accepted Answer

air time

Question 11

Energy is what makes a rollercoaster ride last, but forces are what makes it so thrilling.

Accepted Answer

true

Question 12

When does a coaster have the greatest amount of potential energy?

Accepted Answer

at the top of the first hill

Question 13

If a coaster turns sharply right, what does the inertia cause your body to want to do?

Accepted Answer

keep going straight ahead

Question 14

Velocity is the rate of motion in a specific direction. v=d/t

Accepted Answer

true

Question 15

This picture is an example of...

Accepted Answer

movement of the cannon is less because it has a larger mass., for every action, there is an equal and opposite reaction, Newton's Third Law of Motion

Question 16

For an object to move in a circle, what force is needed to cause the change in direction?

Accepted Answer

centripetal

Question 17

Acceleration is how quickly something is changing velocity.

Accepted Answer

true

Question 18

The amount of energy the coaster has will always be constant this is known as:

Accepted Answer

The Law of Conservation of Energy

Question 19

free-fall is state of plummeting down a hill and there is hardly any net force acting on you.

Accepted Answer

all of the above

Question 20

As you sit in a coaster car waiting for the ride to start, you are being acted upon by...

Accepted Answer

balanced forces

Question 21

The upward pressure of the ground pushes up on your legs & rib cage. This is the feeling of...

Accepted Answer

weight

Question 22

As the car speeds up, you feel pressed against your seat. You feel this force because...

Accepted Answer

your inertia is separate from that of the coaster car.

Question 23

Once you start down the first hill, gravity takes over & _____ energy changes to ____energy.
