How is energy transferred on a roller coaster?

The main energy transfer is when GPE (gravitational potential energy) gets turned into KE (kinetic energy) this happens when the roller coaster car reaches the highest point of the ride and goes down, thus turning GPE into KE at the bottom. After this initial drop, the rest of the drops have to get lower and lower because of the loss of energy.


What happens to a basketball's kinetic energy as it rises toward the basket?

The basketball's kinetic energy begins to turn into potential energy as it reaches the basket.


What happens to solar energy that reaches Earth?

In India we have 300 sunny days - but we ignore this renewable energy to produce electricity.


What part of the roller coaster has kinetic energy?

Mechanical Energy encompasses both Kinetic and Potential energies. A roller coaster is a perfect example of both. At the very top of a hill, the roller coaster has a lot of potential energy due to position above the earth. As it goes down a hill, this potential energy decreases as it gets closer to the earth, and it's kinetic energy increases as it gets faster. KE = energy of motion PE = potential energy due to position above the earth ME = KE+PE

On a Roller Coaster where is the potential energy?

When the roller coaster is at its highest position and is not moving then its potential energy is highest

When does a roller coaster increase kinetic energy?

The roller coaster increases kinetic energy when its velocity is increasing.


How does something turn from kinetic energy to potential energy?

kinetic energy is energy in motion. potential is like a roller coaster you start at the bottom and go up to highest point of the coaster and yougain potential energy as you move to the highest point of the coaster and when you go down the peak point the potential energy the coaster was gaining is transferred to kinetic energy.


What happens to energy from the sun when it reaches the atmosphere and surfaces?

What happens to Solar Energy is that some of it gets absorbed into air, land and water while the rest gets reflected back to space.
