#### Transcript of Roller Coaster Physics!

Physics In Roller Coasters How A Roller coaster Initially Starts Roller coasters have no engine
At beginning of the ride there is a lift that takes the ride up to a high point
be only time a motor is in use and it is only used for that gear and not the actual roller coaster
There are chain lifts, conventional lifts, or a catapult-lunch to start the motion of the coaster
After its at the top of the first hill it must complete the ride on its own How Roller Coasters Continue to move Roller coasters have no engine

The conversion of potential energy to kinetic energy is what drives the roller coaster Roller Coasters depend on two types of energy : Potential & Kinetic
Potential energy: energy that is being stored -As a roller coaster is moving up to the top of the hill it has potential energy Kinetic Energy: energy in motion -when roller coaster descends down the hill The higher the hill the coaster is coming down the more kinetic energy is available to "push" the carts up the next hill, and faster the train will go.

The Affect of Gravity Gravity helps pull the roller coaster down the first hill
-Applies a constant downward force on the cars
Helps coaster stay on path and follow track

Centripetal Acceleration And Centrifugal Force Centripetal acceleration: acceleration that comes from a force that is not in a straight line, rather it is in a circular pattern
HOW IT WORKS ON COASTER..... - Centripetal acceleration points toward the center of the circular path of the train -The passengers feel a force pushing them to the outer edge of the circular path which is described as centrifugal force The centrifugal force is actually your body's inertia and resistance to the train's change in direction your body wants to continue in a straight line and attempts to do so as the train turns. -The centripetal force prevents objects from exiting a curve by continuously making them change their direction toward the center of rotation. -Then Gravity along with the track, pulls down on the cars and the riders with a constant force and keeps the centripetal force needed to keep the cars on the arching path Effect On Rider...

Free Fall And Acceleration If you’re sitting in a roller coaster and it starts to fall down a very high hill, gravity will be pulling you down although the force of acceleration makes you feel as though you are being pushed forward. Sometimes during the ride, these forces can counteract each other, which will make you feel as though you are weightless or free-falling. However, when you are traveling up a very large hill, the two forces will be working in the same direction instead of the opposite ones and this will result in quite the opposite effect on you. Instead of feeling weightless, you will feel very, very heavy as you are ‘sucked’ back into your seat.
