How would the kinetic energy of a 12000-kg train compare with the kinetic energy of a 900-kg compact car if both were traveling at the same speed?
The kinetic energy of the 12000-kg train would be much greater than that of the 900-kg compact car, as kinetic energy is directly proportional to the mass of the object. Therefore, the train would have significantly more kinetic energy than the compact car when traveling at the same speed.
Why does a moving car and train at the same speed not have the same kinetic energy?
While the car and train may be moving at the same speed, their kinetic energies can be different because kinetic energy depends on both the mass and velocity of an object. The train typically has a much larger mass than a car, so even if they are both moving at the same speed, the train will have a greater kinetic energy due to its higher mass.
How much thermal energy is generated by the brakes of a kg train in causing the train to slow from a speed of W sec to speed of W sec?
The amount of thermal energy generated by the brakes of a train in slowing down from one speed to another depends on the mass of the train, the initial and final speeds, and the efficiency of the braking system. The energy is converted from the kinetic energy of the train into heat energy by the brakes. The specific calculation would require more details about the system.
What energy transformation does train have?
A train has mechanical energy in the form of kinetic energy as it moves. This kinetic energy comes from the conversion of potential energy stored in the fuel it burns to power its engine.
Who has transferred the most kinetic energy to his surroundings?
An object with a large mass and a high velocity would transfer the most kinetic energy to its surroundings. For example, a speeding train or a moving car would transfer a significant amount of kinetic energy due to their mass and speed.

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.
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.

Is a train motion energy?
Yes, a train in motion possesses kinetic energy, which is the energy associated with its movement. This kinetic energy is generated by the train's engine converting stored potential energy (from fuel or electricity) into motion.
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-?
False. Kinetic energy is indeed the energy possessed by a body in motion, not by a stationary object. The energy exhibited by a stationary train would typically be in the form of potential energy, such as gravitational potential energy due to its position on the tracks.
Why does a speeding bullet and a 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?
When a moving train stops, its kinetic energy is primarily converted into heat energy due to friction between the train's brakes and the track. Additionally, some kinetic energy may also be converted into sound energy and vibration energy during the process of stopping.
