A generator converts mechanical energy into electrical energy, while a motor does the opposite – it converts electrical energy into mechanical energy. Both devices work because of electromagnetic induction, which is when a voltage is induced by a changing magnetic field.
What can change mechanical energy into electrical energy?
A generator converts mechanical energy into electrical energy. A hydroelectric powerplant converts the mechanical energy of water in a storage dam into electrical energy.
What is an example of electrical energy to mechanical energy?
An electric motor converts electrical energy into mechanical energy. A generator converts mechanical energy into electrical energy. A hydroelectric powerplant converts the mechanical energy of water in a storage dam into electrical energy.
What is electrical energy and mechanical energy?
Kinetic Energy can be defined as the energy possessed by the object by the virtue of its motion. The sum of these two energies is often called Mechanical Energy of the System. … Electric Energy is also a form of these 2 energies: Electric potential energy stored in a charged particle in an electric field.
Does vacuum cleaner converts electrical energy into mechanical energy?
An electric motor from an old vacuum cleaner. … An electric motor is a device used to convert electricity into mechanical energy—opposite to an electric generator.
Is a device that converts electrical energy into rotational mechanical energy?
The most common device for changing electrical energy into mechanical energy is the motor. Most motors use electromagnets to cause mechanical rotation, which can do work.
What is a device that converts chemical energy to electrical energy?
A battery is a device that converts chemical energy contained within its active materials directly into electric energy by means of an electrochemical oxidation-reduction (redox) reaction.
What are 5 examples of energy transfer?
- A swinging pirate ship ride at a theme park. Kinetic energy is transferred into gravitational potential energy.
- A boat being accelerated by the force of the engine. The boat pushes through the water as chemical energy is transferred into kinetic energy.
- Bringing water to the boil in an electric kettle.
What are the 2 types of mechanical energy?
Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position).
What are some examples of electrical energy?
Here are some examples of everyday objects that use electrical energy.
- Washing machine.
- Cell phone.
- Air conditioning system.
- Heating system.
