Electrical energy, converted to mechanical energy by an electric motor.
Electric toothbrushes themselves do not decrease cavities. Cavities are more likely to form in the areas a person does not reach with their regular brush. Some do just fine with a regular manual brush where others do better with the electric.
Good question. I would say it's called tooth brush because of the size of the brush. Technically, it really only brushes one tooth at the time, hence a teeth brush would be longer and more cumbersome to use in the mouth.
Electric energy is a form of kinetic energy, as it is the energy associated with the movement of electric charges.
The potential energy of an electric fan is typically in the form of electrical potential energy. This energy is stored in the fan's electric circuit when it is connected to a power source.
when we clean our teeth we brush it...
It is important to brush your teeth because plaque can build up on your teeth. When enough plaque builds up on a tooth it can form a hole in your tooth known as a "cavity". A cavity causes bad breath, and its very embarrising when you open your mouth.
The rate at which electric energy is converted to another form is measured in watts (W) or kilowatts (kW). This conversion rate depends on the efficiency of the device or system that is transforming the electric energy into another form, such as heat, light, or mechanical energy.
Electric cables carry electrical energy in the form of electricity.
