The correct answer is:
Kinetic energy transfers to potential energy, then some potential energy transfers to kinetic energy.
The correct answer is: Potential energy transfers to kinetic energy, then some kinetic energy transfers to potential energy.
The correct answer is: Potential energy transfers to kinetic energy, then some kinetic energy transfers to potential energy.
To understand this energy transformation, we need to understand the concept of potential energy and kinetic energy.
Potential energy is the energy an object possesses due to its position or condition. In the case of the roller coaster, when it is at the highest point (point X), it possesses a high amount of potential energy due to its elevated position.
Kinetic energy, on the other hand, is the energy an object possesses due to its motion. As the roller coaster moves from point X to point Y, its potential energy gradually decreases, while its kinetic energy increases. At the lowest point (point Y), the roller coaster possesses maximum kinetic energy and minimum potential energy.
So, initially at point X, the roller coaster has high potential energy and low kinetic energy. As it moves downwards, the potential energy decreases, and the kinetic energy increases due to the conversion of potential energy into kinetic energy. This is known as the transfer of energy.
However, at some points during the roller coaster ride, such as during loops or hills, the roller coaster may gain or lose potential energy. For example, when the roller coaster goes up a hill, it gains potential energy as it moves higher against the force of gravity. And when it goes down a hill or loop, some kinetic energy transforms back into potential energy as it gains speed or moves upwards against gravity.
Overall, the energy transformation in a model roller coaster involves the transfer of potential energy into kinetic energy, and then back into potential energy at certain points during the ride.
