A rollar coaster is a good example of electricitiy because on a roller coaster its easy to see where POTENTIAL and KINETIC energry fall.
Roller coaster pieces can fall off, although it very unlikely. A roller coast is a piece of machinery and can break of malfunction like anything else. For safety reasons, roller coasters undergo rigorous inspections and frequent maintenance so the chances of a piece falling off is extremely unlikely.
its when a rollercoaster runs at very fast speed with out it being controlled by machines.
1.The Rollercoater could get stuck 2. You could fall off the rollercoater 3. Someone could have a heart attack and die while riding the rollercoater 4. The coaster tracks could break and the coaster and all of the riders will fall to the ground 5. The coaster could come off the tracks and go flying through the air before colliding with the ground. ^_^
The rapid change and rise and fall of air pressure sends certain signals to our brain so we can feel the adrenaline that usually comes with riding a roller coaster.
Why would they? Mine have never just fallen out unless I stare at something for about 2 minutes. I have ridden a rollar coaster with mine in, and they stayed in. If you are very concerned about this, you might want to just ask your eye doctor next time you go in to buy more contact lenses.
Modern roller coasters are quite safe; they have many checks and are monitored often to ensure they remain safe. However, ride accidents do occur. People who aren't riding can be hit by the coaster if they enter the coaster area. As well, people who are too small can fall out of the ride if they aren't secured safely.
Well in roller coasters there is potential and kinetic energy. So when the roller coaster is getting pulled up it is using kinetic energy while gaining potential energy. So the potential energy it gained is used while going down and not being pulled.
According to Newton's first law of motion, a body will continue in its state of uniform motion along a straight line when there is no net force acting on it. That means if the roller coaster is under no external forces, it would move in a straight line tangential to the track. However, there should be forces acting on it because its direction of motion changes. Assuming that the mass of the roller coaster is, it is moving at a velocity, and the track is circular with a radius, the centripetal force required would be
Gravatational and Potential Energys are the same, they simply both have the potential to fall (its higher up) and Kintic Energy is was is created when for example a roller coaster moves?! I has Kinetic Energy and some is lost throughout sound and heat as thats is another type pf energy that is created when a roller coaster moves.
A roller coaster ride will exhilarate me.A brisk, fall day might exhilarate you. A million dollars would exhilarate anyone.
Because Roller Coasters are required to have harnesses, belts, or other such things to keep your strapped in when they go.
