Heat, from the friction in the brakes.

∙ 13y agopotential energy. This would apply if the train is going up an incline, and did not use mechanical brakes. On the flat, the KE is converted to thermal energy in the brakes

When a moving train stops kinetic energy is changes to what kind of energy?
Heat energy cause it stops and let's off all the heat it just gained from the train tracks.
What does mechanical energy in own words?
Mechanical energy is a combination of its potential and kinetic energy. For example when a goes forward that is potential energy when it stops that is kinetic energy. thanks(:
What happens to a sample of matter when its particles lose kinetic energy?
A loss of kinetic energy in the atoms or molecules of a sample of matter will result in the cooling of the sample. That sample will get colder as remove thermal energy from it. The atoms/molecules of a substance have kinetic energy associated with them. This kinetic energy is the result of atomic and/or molecular motion. As a sample of matter cools, the atoms and/or molecules will lose mobility. Loss of mobility and vibrational energy, which are forms of kinetic energy, will become apparent when thermal energy is removed from the sample.
What situation does not involve Potential energy being changed into kinetic energy?
1) Kinetic energy being turned back into potential energy. Look at a child on a swing. As the swing lowers (and they speed up), that's potential to kinetic. As the swing reaches its peak and stops, that kinetic to potential. 2) Burning is chemical energy being turned into heat and light. 3) In the Sun, nuclear fusion releases energy into heat and light.
How potential and kinetic energy have been used by the planet and living organisms?
Potential energy and Kinetic energy are used by the planet by our orbit. Earth has Gravitational potential energy and so do the other planets. When a bigger object with a gravitational field comes close to a planet or rock it is pulled into the field. The planet keeps wanting to go straight, but the field keeps it in orbit. Therefore the planet is always using potential and kinetic energy to stay in orbit. EDIT: Potential is the energy inside matter when it is not moving, and kinetic is inside when it is moving. For example; if a boulder is sitting on a cliff, it is potential. Then it falls and goes down. It is moving, so it is not kinetic. Then it stops moving, and it is potential again. So the Earth is moving, using the kinetic energy. Some of the life forms(like a person sitting doing nothing) on Earth are potential. The energy flow through living organisms starts with sunlight and photosynthesis, then travels through the food chain in bite sized chunks. Primary producers, primary consumers, secondary consumers, and decomposers are all part of the food chain.
When a moving train stops kinetic energy is changed to?
heat energy in the breaks. The breaks heat up.
A glass of water is stirred and then allowed to stand until the water stops movingwhat has happened to the kinetic energy of the moving water?
The kinetic energy has been transformed into potential energy as the water slows down and stops moving.
When pendulum stops has the kinetic energy changed to potential energy?
As the pendulum stops swinging, its maximum kinetic energy (the initial energy at the beginning of the swing) decreases, and its potential energy increases. Once the pendulum stops, it will have zero kinetic energy and maximum potential energy.
When a moving train stops kinetic energy is changes to what kind of energy?
Heat energy cause it stops and let's off all the heat it just gained from the train tracks.
What happens to the kinetic energy of a machine when it stops?
the kinetic energy that is being used simply changes then into wate energy
When a ball stops moving does it lose its energy?
It loses it's kinetic energy, the energy of motion. If it were logded against a rock on a hill, it has potential energy stored because of it's position on the hill.
What does mechanical energy in own words?
Mechanical energy is a combination of its potential and kinetic energy. For example when a goes forward that is potential energy when it stops that is kinetic energy. thanks(:
What happens to kinetic energy when a machine stops?
It is converted into mostly potential (stored) energy.

Give an example of a transformation of energy kinetic potential is?
===> A stone or a baseball tossed straight up.-- Leaves your hand with speed ---> has kinetic energy-- Slows down as it sails higher ---> loses kinetic energy-- But gains potential energy as it moves higher.-- The kinetic energy it's losing is changing into potential energy.-- Eventually, it stops rising, when all of its kinetic energy is gone.-- On the way down, its potential energy turns back into kinetic energy,until it meets the ground, at a healthy speed and with a healthy 'thunk'.A pump filling a water reservoir with water below the reservoir level.Easy to use the turbine to convert it back to kinetic energy.A bike rider stops pedaling and lets his bicycle coast up a hill.Kinetic energy is the energy any object possesses due to its movement. Any moving object has KE.Potential energy is the energy an object has due to its position. A weight, lifted up, has potential energy due to its ability to fall down and hit something.
Does a rolling ball eventually lose it energy?
No. It has potential energy once it stops. and when it moves, it has kinetic energy. it always has energy
