energy is not produced, created or destroyed - it is converted. in the case of the rollercoaster it could be from electrical energy from the motor to move it, or from gravitational energy as it goes down a slope. the formula for workig out the kinetic energy an object has is: [1/2 x mass x (velocity squared)]
Kinetic energy comes from movement. If the roller coaster is moving at the top of the hill, it has kinetic energy. if the rollercoaster isn't moving then it has potential energy.
If its moving it has kinetic energy
yes kinetic energy is energy being released, for example going down a roller coaster
Kinetic energy is produced by moving particles. This energy is a form of energy that an object possesses due to its motion. The kinetic energy of an object increases as its speed or mass increases.
On a pendulum, the greatest potential energy is at the highest point of the swing on either side, and the greatest kinetic energy is at the bottom of the swing. On a roller coaster, the greatest potential energy is at the top of a hill, and the greatest kinetic energy is at the bottom of the hill.
running uses kinetic energy. * kinetic energy:is the energy produced by a moving object or when someone is moving. * runnung needs 60 kilojoules of energy for every minute you run.
Hydroelectric Power
Any moving object has kinetic energy.
Kinetic energy is the energy produced by moving parts. This type of energy is generated when an object is in motion due to its velocity and mass. Examples include a rotating wind turbine generating mechanical energy or a moving car producing kinetic energy.
The potential energy is highest at the top of the first hill or peak of the roller coaster because it is at its maximum height above the ground. As the roller coaster descends, potential energy is converted into kinetic energy as the car gains speed.
Potential energy becomes kinetic energy when the car begins its downward descent from the top of one of the rollercoaster's peaks. It accumlates potential energy as it is lifted to the first and highest peak. It regains some of its lost potential energy each time it re-ascends one of the lower peaks, then loses potential and gains kinetic energy as it drops again.
If it is a rollercoaster that has a first drop hill, the roller coaster has the greatest kinetic energy at the bottom of that drop. If it is magnetically launched, the kinetic energy is probably greatest immediately after the launch. However, there are cases where these statements may not be true. (i.e. a drop right after a magnetic launch)The energy is the greatest at the bottom of a drop, before some is translated back into potential energy as the car climbs the next rise.
