Energy Transformations

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting electrical energy into thermal energy.

Front

What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed; it can only change forms.

What type of energy does a microwave oven primarily transform electrical energy into?

Back

A microwave oven primarily transforms electrical energy into thermal energy.

Front

What is an example of a device that transforms electrical energy into mechanical energy?

Back

A pencil sharpener is an example of a device that transforms electrical energy into mechanical energy.

Front

What energy transformation occurs in a flashlight when it is turned on?

Back

The energy transformation in a flashlight is chemical energy (from batteries) to electrical energy to light energy.

Front

What is fission in the context of nuclear energy?

Back

Fission is the process of splitting uranium atoms to release a large amount of energy, which is then converted into electricity.

Front

What type of energy is produced by a nuclear power plant?

Back

A nuclear power plant produces electricity as a result of energy transformations.

Front

What is an example of energy transformation in a battery-operated toy?

Back

In a battery-operated toy, chemical energy from the batteries is transformed into mechanical energy to make the toy move.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter; it is the total kinetic energy of particles in an object.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object, enabling it to do work.
