Is sign a potential energy or a kinetic energy?

It is potential energy because it is waiting to be moved.


What happens to sample of matter when its particles lose kinetic energy?

its particles stop moving around because of loosing kinetic energy. As you know kinetic energy is something that moves around .And particles in sample of matter cool off and stop.


A rollar coaster stop at the top of the hill What can you infer about its kinetic energy?

The roller coaster does not have kinetic energy at the top of the hill


How do brakes stop a car?

Friction converts kinetic energy into heat energy.


How does kinetic energy stop?

Kinetic energy is the energy of motion. Energy cannot be destroyed, but it can be converted into other forms. When you want to get rid of kinetic energy, we normally use a brake, which converts the kinetic energy into heat energy through friction. With some hybrid automobiles, they use "regenerative braking" to convert the kinetic energy of motion back into electrical energy in the batteries.


What are the energy transformations of a roller coaster that comes to a stop?

Its a transformation of kinetic energy to potential energy.


What is the kinetic energy of the free falling object that eventually stop on reaching the ground?

Once the object has reached the ground, its kinetic energy is zero.


Is flowing water kinetic or potential energy?

well when you swim you are moving witch has to do with konetic ,and patenchal is when u stop and store the energy soo the awnser is yess


What type of energy occurs when you hit the brakes on a bike?

i think it is kinetic energy to thermal energy.


Can kinetic energy be converted into elastic energy?

Certainly. That's exactly what happens when you fall into the middle of a trampoline. As the stretchy fabric absorbs your kinetic energy, you slow down, and you eventually stop when all of your kinetic energy is stored in the trampoline as elastic energy. Then the elastic energy transfers back and becomes your kinetic energy, as you go sailing again.


The car has 1000 kg mass and it was going 20 ms before it stopped at the stop sign what is its potential energy?

Before the driver hit the brakes, the car's kinetic energy was (1/2 m V2) = (500) (20)2 = 200,000 joules.After it stops at the stop sign, its kinetic energy and potential energy are both zero. The brakesturned that whole 200,000 joules into heat, and the wind blew it away.Unless . . .Unless the car is an electric or a hybrid. What they do is to take that kinetic energy and puta lot of it back into the battery, so you can use it again, and you don't completely lose it all.That's what's the big deal about electric and hybrid cars.


What kind of energy in car engine?

Chemical energy is being converted to thermal energy which is then converted to mechanical energy and finally to kinetic energy which moves the car. Kinetic energy is then converted to thermal energy in the brakes to stop the car.
