What device can change kinetic energy into potential energy?
Any ramp can.
An electric motor converts electrical energy to potential energy?
They don't. An electric motor is designed to convert electrical energy to kinetic energy, not the other way round. A device that converts kinetic energy to electrical energy is called a generator or a dynamo. Sometimes the same device can do both things (convert in both directions), but since the device is especially optimized for one function, it may not be very good at the other one.
How does connecting an electric device to a battery produce an current in the device?
If we connect a battery to a device and complete a circuit, current will flow in that circuit and through the device. A battery (in good condition) is an electrical storage device. Most of the ones we are familiar with are chemical cells. There are chemicals inside that would like to react, but cannot unless there is an external circuit through which electrons can move to get from one electrode in the battery to the other. The potential chemical energy in a battery can be converted into electrical energy by completing that circuit. There is a force called voltagethat arises between the electrodes of the battery. And this voltage (electromotive force, or EMF) is the way that the chemical potential energy expresses itself. Because the battery can convert chemical potential energy into electricity owing to that EMF between the electrodes, connecting a circuit across the battery will allow current to flow as the chemical reactions in the battery proceed. A very rough analogy can be drawn by looking at gravitational potential energy. If a bowling ball is sitting on the floor and it is lifted onto a table, its gravitational potential energy has been increased. This is distantly similar to the chemical reactions that want to occur in the battery; they are potential energy, too. If the bowling ball rolls off the edge of the table, the potential energy is converted into kinetic energy by gravity. When we hook up an external circuit to the battery, the chemical potential energy (expressed as voltage) drives electrical current through that circuit and the device in it. The circuit here is composed of conductors and the device. Electrons in the conductors are hanging around in the conduction band, and if a voltage is applied, those electrons will begin moving in response. The device must be conductive to some extent, and it, too, will have this electron current flowing through it. The battery has been connected to a circuit and drives current through that circuit. The chemical potential energy in the battery is converted into electrical energy in the circuit and the device connected to it.
What is a device that changes thermal energy into mechanicl energy?
A steam engine.
What is seismic damper?
A seismic damper is a mechanical device that dissipates kinetic energy of seismic waves. It is also known as a harmonic absorber.
How does elastic energy changes to potential energy?
''how does elastic potential energy work in a ball?'' can you just tell me now at school. and who are you,are u just a computer and they put everythink in you or what are you some smart guy/girl
What device can change kinetic energy into potential energy?

A what is a device that changes kinetic energy into electrical energy?
A generator in a power plant converts rotating kinetic energy into electrical energy An electric motor is a device which changes electrical energy into kinetic. For example-- Fans could be like electric energy to kinetic energy...
What device that transforms gravitational energy to kinetic energy?
Anything that falls. Some examples are: -- A waterfall -- A ball rolling down a hill -- A sailplane, when it is NOT climbing in a thermal -- Any pendulum, when it is moving TOWARD the center of its swing -- Anything you drop. The gravitational potential that it has relative to the floor while you're holding it in your hand is exactly the kinetic energy it has when it hits the floor.

How does a roller coaster demonstrate potential and kinetic energy in action?
there is a lot of potential energy right before a roller coaster decreases in elevation. potential energy is at its highest on a roller coaster when the roller coaster is at its highest point. when it drops down it uses kinetic energy.

A device that converts kinetic energy to electrical energy is called a generator or a dynamo.

What is antigravity device?
That refers to a HYPOTHETICAL device that will cancel the gravitational field.
Which device is used for converting potential energy into kinetic energy?
There is no "device" that is used to convert potential energy (PE) to kinetic energy (KE). PE is energy of position, for example, a bowling ball held over your head has the potential of breaking your foot if it were to fall. KE is energy of motion, for example, the energy the bowling ball has as it is falling toward your foot. The amount of PE the bowling ball had when it was motionless at some height above your head is approximately equal to the amount of KE the bowling ball has just before it lands on your foot.
Is energy changing forms when an electrical device is plugged in and using energy?
Not just that ,like if your just sitting down you're using potential energy and when you start moving it becomes Kinetic energy
