the car looses potentional force and gains kinectic and sound :)
Yes,because it is moving
A roller coaster increases kinetic energy when it is going downhill, as gravity is pulling it down and accelerating it. The potential energy is converted into kinetic energy as the roller coaster gains speed.
Saddle up
Yes. At the top of the hill, the potential energy is at a maximum. As the coaster is rolling down the hill, the potential energy (or energy due to the coaster's position or height), is converted into kinetic energy (as the roller coaster is rushing downhill). Hope this helps, physicsisland@hotmail.com
Potential energy is gained as the roller coaster car goes up to the top of the first hill. This type of energy is due to the car's height above the ground and its potential to do work as it moves downhill.
The smallest roller coaster at Cedar Point is Wilderness Run. It is a kiddie roller coaster that is only 19 feet tall and goes 6 mph.
Something that has variable motion travels different distances/ speed in equal periods of time. Going uphill, roller coasters are sort of slow but going downhill, the roller coaster starts to accelerate. The roller coaster takes the same track every time and only goes through it once so, it has equal time periods. By traveling at 2 different speeds during equal time periods, you have variable motion.
Either stay off the roller coaster, or keep riding it until the fear goes away.
Gravity is pulling the coaster downwards, "what goes up must come down."
The PNE Wooden Roller Coaster goes about 45km/h
The plural is underwater roller coasters. The word underwater is an adjective describing roller coaster, adjectives don't take plural forms. Roller coaster is an open compound noun, the plural 's' goes on the end of the noun.
