Energy Transformations

Front

What are energy transformations?

Back

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

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 kinetic energy (energy of motion) and potential energy (stored energy) in an object.

Front

Can energy be created or destroyed?

Back

No, according to the law of conservation of energy, energy cannot be created or destroyed, only transformed from one form to another.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules.

What happens to electrical energy in a microwave oven?

Back

In a microwave oven, electrical energy is transformed into thermal energy to heat food.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, depending on its mass and speed.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as a stretched spring or an object at height.

What is an example of energy transformation in a hot air balloon?

Back

In a hot air balloon, chemical energy from the fuel is transformed into thermal energy to heat the air, which then transforms into mechanical energy to lift the balloon.

What type of energy transformation occurs when a fan is turned on?

Back

When a fan is turned on, electrical energy is transformed into mechanical energy.
