Forms of Energy and Transformations

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object. It is the energy associated with the motion and position of an object.

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 the particles in an object.

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 electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It is commonly used to power devices and appliances.

Front

What is nuclear energy?

Back

Nuclear energy is the energy released during nuclear fission or fusion, especially when used to generate electricity.

Front

What is an example of energy transformation?

Back

An example of energy transformation is when electrical energy is converted into thermal energy in a toaster.

Front

What happens to energy when a wind turbine spins?

Back

When a wind turbine spins, kinetic energy from the wind is transformed into mechanical energy.

Front

What is the energy transformation when riding a bike uphill?

Back

The energy transformations when riding a bike uphill are chemical energy (from food) to mechanical energy (movement) and thermal energy (heat).

Front

What is the relationship between potential and kinetic energy?

Back

Potential energy is stored energy based on an object's position, while kinetic energy is the energy of motion. They can transform into each other.

Front

What is an example of thermal energy in everyday life?

Back

An example of thermal energy is the heat produced by a stove when cooking food.
