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 are the main forms of energy?

Back

The main forms of energy include kinetic energy, potential energy, thermal energy, chemical energy, electrical energy, and nuclear energy.

What energy transformation occurs in a microwave oven?

Back

In a microwave oven, electrical energy is transformed into electromagnetic energy (microwaves), which is then transformed into thermal energy to heat food.

What energy transformation occurs when propane gas is burned?

Back

When propane gas is burned, chemical energy is transformed into thermal energy and then into mechanical energy.

What happens to the chemical energy in a match when it is struck?

Back

The chemical energy stored in the match is transformed into thermal energy and light energy when it is struck.

Front

What energy transformation occurs when a flashlight is turned on?

Back

When a flashlight is turned on, chemical energy from the batteries is transformed into electrical energy, which is then transformed into light energy.

Front

What energy transformation occurs in a wind turbine?

Back

In a wind turbine, mechanical energy from the wind is transformed into electrical energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its mass and velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, such as gravitational potential energy.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, which is the total kinetic energy of particles in a substance.
