    Example: Friction on the roller-coaster car. The roller-coaster car shown reaches a vertical height of only 25 m on the second hill before coming to a momentary stop. It traveled a total distance of 400 m. Determine the thermal energy produced and estimate the average friction force (assume it is roughly constant) on the car, whose mass is 1000 kg. Energy cannot be created or destroyed, but it can transfer from one form of energy to the next. Energy takes on a wide variety of forms. Thermal (heat) energy is caused by the vibration of atoms with a substance. Nuclear energy is given off when the nuclei of atoms are either combined or split. Electrical energy is a rapid movement of electrons. The car has _____energy. Calculate it. 4. A cinder block is sitting on a platform 20 m high. It weighs 79 N. The block has _____ energy. Calculate it. 5. There is a bell at the top of a tower that is 45 m high. The bell weighs 190 N. The bell has _____ energy. Calculate it. 6. A roller coaster is at the top of a 72 m hill and weighs 966 N. How do gravity and potential energy work together to give you a great ride on a roller coaster? As the coaster gets higher in the air, gravity can pull it down a greater distance. When going downhill gravity takes over and all the built-up potential e­nergy changes to kinetic energy.

    6. A roller coaster is at the top of a 72 m hill and weighs 966 N. The coaster (at this moment) has energy. Calculate it. 7.

In a real roller coaster, the car is pulled to the top of the first hill and then released. What must be true of all the other hills in the roller coaster? 3. Well, there is no formula because it is a complicated problem. However, if friction is negligible and the roller coaster starts from rest at a distance h above the bottom, you can estimate the speed at the bottom using energy conservation, mv 2 /2=mgh where m is the mass and g is the acceleration due to Roller coasters rely on gravity to take them to the end of the track. This involves two types of energy, potential energy and kinetic energy. The maximum kinetic energy generated is when the roller coaster is at the bottom of the track. When it begins to go up, the kinetic energy converts to potential...

Any object in motion is said to have kinetic energy. A roller coaster has kinetic energy as it moves up, over, and down the track. The amount of kinetic energy depends on the train's location. As the train moves along the track, the energy the train has is transformed from kinetic energy to potential energy, back and forth ... point, all of its energy is potential energy. Conservation of energy says to set the initial energy equal to the energy of the point you’re interested in: E final = 1 2 mass∗(speed)2 +mass∗g∗height. If we want the speed as large as possible, we want the height at that point to be as small as possible - that means more of its energy is kinetic energy.
