Why does a train have more kinetic energy than a car traveling at the same speed?
Kinetic energy also depends on mass.
True or false kinetic energy is energy possessed by a body in motion the form of energy shown by a stationary train is kinetic energy-?
Kinetic energy is possessed by a moving body, that is true. But if the train is stationary it cannot have kinetic 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.
When a moving train stops kinetic energy is changed to which kind of energy?
Heat, from the friction in the brakes.
What is the difference between kinetic energy potential energy and mechanical energy?
Potential energy is energy that has the potential to be moved. Kinetic energy is energy in motion. eg. Potential energy could be like a fire extinguisher that is on the wall it has the potential to fall on the ground . An example of Kinetic energy is would be a moving car, it is in motion .
Why does a train have more kinetic energy than a car traveling at the same speed?
Kinetic energy also depends on mass.
Why does a speeding bullet and a moving train have so much force?
Each of those items has large momentum and kinetic energy ... the bullet because of its high speed, and the train on account of its large mass.
When a moving train stops kinetic energy is changed to?
heat energy in the breaks. The breaks heat up.

Why does a train have more kinetic energy then a car?
Kinetic Energy = 1/2 mv2 where m = mass and v = velocity A train has much more mass than a car. So even if they are travelling at the same speed, a train will have more kinetic energy than a car.
What is an example of of an object with kinetic energy?
Kinetic Energy is the energy of motion, so anything that is moving has kinetic energy. Examples : a ball rolling down a ramp a spoon falling off a table a Baseball hurtling towards a window a moving train a coin falling from the roof of a building (generally anything with a rest mass which isn't at rest)
If you are moving to the front of a moving train are you moving faster than the train relative to the earth?
Yes if the train is moving forward, you are moving at the train speed + walking speed relative to the tracks.
How does a roller coater changes speed?
as the rollar coaster goes up the "hill" as far as it can go , it is considered. Once there it goes down hill and becomes kinetic energy. The roller coaster changes speeds because of the series of hills it goes up and falls down. At the top of the first lift hill (a), there is maximum potential energy because the train is as high as it gets. As the train starts down the hill, this potential energy is converted into kinetic energy -- the train speeds up. At the bottom of the hill (b), there is maximum kinetic energy and little potential energy. The kinetic energy propels the train up the second hill (c), building up the potential-energy level. As the train enters the loop-the-loop (d), it has a lot of kinetic energy and not much potential energy. The potential-energy level builds as the train speeds to the top of the loop (e), but it is soon converted back to kinetic energy as the train leaves the loop.
When a moving train stops kinetic energy is changed to which kind of energy?
Heat, from the friction in the brakes.
When does the skier have the greatest potential energy?
Just standing there, a skier on the top of the mountain has potential energy. If she uses her poles to push-pull before taking off, she's building up a small amount of kinetic energy. If a skier is then moving down the mountain, his movement downward is kinetic energy which increases as his speed increases. If he or she collides with an immovable object while skiing, kinetic energy abruptly ends. If he or she takes off from the top of the mountain and an avalanche happens to hit at the same time, the kinetic energy of the avalanche engulfs the skier and overpowers the lower kinetic energy of the skier. The skier and avalanche become as if one in the kinetic force of the avalanche--until the skier collides with something or is buried, and thus is separated from the avalanche's kinetic energy which continues until the avalanche stops.
