Transfer of Energy Level 3

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It has the potential to be converted into kinetic energy.

Front

What are the types of potential energy?

Back

The main types of potential energy include gravitational, elastic, chemical, and nuclear energy.

Front

What is gravitational energy?

Back

Gravitational energy is the potential energy held by an object because of its height above the ground. The higher the object, the more gravitational energy it has.

Front

What is electromagnetic energy?

Back

Electromagnetic energy is a form of energy that is reflected or emitted in the form of electrical and magnetic waves that can travel through space.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules. It is released or absorbed during a chemical reaction.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object that is used to do work.

Front

What is thermal energy?

Back

Thermal energy is the internal energy present in a system due to its temperature. It is the energy that comes from the movement of atoms and molecules.

Front

How does a wind turbine work?

Back

A wind turbine converts the kinetic energy of wind into mechanical energy, which is then transformed into electrical energy.

Front

What is energy transformation?

Back

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

Front

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

Back

In a hot air balloon, chemical energy from propane is transformed into thermal energy (heat), which then creates mechanical energy that lifts the balloon.
