CEDAR POINT FINAL

Non-Looping Roller Coaster Identify at least three sources of friction in this ride.

Tracks on the Coaster Passenger and Seat Hands on bar

Non-Looping Roller Coaster Is climbing the first hill potential or kinetic energy?

Potiential Energy

Ferris Wheel What does the spring accelerator read at the top?

.7g

Ferris Wheel What does the spring accelerator read when going up?

1.1g

Ferris Wheel What does the spring accelerator read when at the bottom?

1.2g

Ferris Wheel When and where does a passenger feel the lightest? Why?

A passenger feels the lightest at the top of the arc. Because of Centripetal acceleration.

The Pirate Ship Describe your energy at the following point? At the highest point

Potential Energy is at its highest point, theres no kinetic energy.

Non-Looping Roller Coaster Which of Newtons Laws would allow a passenger to fly right out of his seat if he did not have a lap belt over him and the roller coaster suddenly stopped?

First Law

Ferris Wheel When and where does a passenger feel the heaviest?

Heaviest at the bottom of the arc. Less gravity on top; gravity pulls you down at the bottom.

The Pirate Ship Describe your energy at the following point? Halfway, going down

Potential energy decreases Kinetic Energy Increases

Non-Looping Roller Coaster The rollercoaster is able to travel up the second hill because of what physics concept?

Inertia, potiential -> kinetic energy

Merry-Go-Round Is this acceleration of you traveling on the merry-go-round inward or outward?

Inward Acceleration

Looping Roller Coaster While screaming as you reach the top of the loop, your retainer falls out of your mouth. Which way does it go from your frame of reference? Why?

It goes UP because you think you're standing.

Looping Roller Coaster While screaming as you reach the top of the loop, your retainer falls out of your mouth, which way does it go from the grounds frame of reference? Why?

It goes down because gravity is pulling it down and the grounds frame of reference

Non-Looping Roller Coaster Is going down the hill potential or kinetic energy?

Kinetic Energy

The Pirate Ship Describe your energy at the following point? Moving through the lowest point

Kinetic Energy is at its maximum, theres no potential energy.

The Pirate Ship Describe your energy at the following point? At rest

Kinetic and potential energy tend to not be doing much.

Bumper Cars During collisions, is kinetic energy always conserved? Please explain your answer.

Kinetic energy is converted into heat and sand. Not always conserved. It is conserved in elastic collisions, but it is converted into other forms of energy during an inelastic collision.

Bumper Cars What happens to the passengers in each car in a collision when one bumper car is not mocing there is a collision with a stationary object, such as a wall?

Passengers will give an equal and opposite reaction, [bounce forward and backward]

The Pirate Ship Describe your energy at the following point? Halfway, going up

Potential Energy increases, kinetic energy decreases.

Merry-Go-Round Explain how the ride might be altered to achieve a greater speed without using a more powerful motor?

Some weight can be taken off the merry-go-round.

Merry-Go-Round How does the centripetal acceleration depend on the distance from the center of the merry-go-round?

The centripetal acceleration basically depends on the radius the higher the radius the faster the force, also, the farther you are from the center the faster and more force you have, the closer to the center the less force an slower.

Bumper Cars What happens to the passengers in each car collision when one bumper is not moving and a HEAD-on collision occurs?

The passengers will bounce backwards.

Non-Looping Roller Coaster Why is the second hill shorter than the first?

The second hill is shorter than the first because there needs to be enough energy to make the entire second loop.

Merry-Go-Round How does the centripetal acceleration depend on the height the passenger is above the ground?

There is no dependence/correlation

Non-Looping Roller Coaster Which of Newtons Laws is your body bouncing back into your seat after hitting the lap bar an example of?

Third law [Equal and proportional]

Bumper Cars In terms of momentum and impulse, why do the cars have rubber bumpers?

To slow down momentum and decrease force of impact by increasing time.

MaXair or Wave Swinger Describe where in the course of the ride's motion your legs are down.

When a turn occurs or when it's at rest.

Merry-Go-Round At what point in their motion do the passengers on the carousel obtain their maximum tangential velocity? Please Explain.

When moving the fastest.

MaXair or Wave Swinger With your legs still relaxed, describe where in the course of the rides motion your legs tend to be moved away from your body and the base of the seat

When the ride's moving in a parabolic shape.

Bumper Cars What happens to the passengers in each car collision when one bumper is not moving and a REAR-END collision occurs?

You both move forward.

Ferris Wheel What does the spring accelerator read when going down?

between .8g and .9g

The Pirate Ship Does this ride follow the rules for a simple pendulum?

yes, because the length and the period to move are always equal. [Always the same]
