What is energy transfer?

Back

Energy transfer is the process of moving energy from one place to another or transforming it from one form to another.

Front

What is thermal energy?

Back

Thermal energy is the energy produced by heat, which is the result of the movement of particles in a substance.

Front

What is an example of electrical energy transfer?

Back

An example of electrical energy transfer is when electricity powers a microwave, converting electrical energy into thermal energy.

Front

What is mechanical energy?

Back

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

Front

What happens when a turbine spins?

Back

When a turbine spins, it converts mechanical energy into electrical energy.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food, which can be released during a chemical reaction.

Front

What is an example of energy transfer in a television?

Back

In a television, electrical energy is converted into light and sound energy.

Front

What is the difference between potential and kinetic energy?

Back

Potential energy is stored energy based on an object's position, while kinetic energy is the energy of an object in motion.

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.

Front

What is the role of energy in physical changes?

Back

Energy is required to change the state of matter, such as melting ice into water, which involves thermal energy.
