This task is about energy transformation.

Some objects such as an aeroplane, have the potential to transfer or transform energy.

Types of energy
chemical potential	gravitational potential	heat	sound	kinetic

Use the energy types in the box above to answer the following questions.

Question 2Change answer

a) What is the main energy change occurring to the chemical potential energy in the aeroplane

when it is flying at a constant altitude?

a) What is the main energy change occurring to the chemical potential energy in the aeroplane

when it is flying at a constant altitude?

From chemical potential energy to chemical potentialgravitational potentialheatsoundkinetic energy. (Select one)

b) What is one main energy change that occurs when the aeroplane increases height?

From energy to energy.

c) What is one main energy change that occurs when the aeroplane lands?

From energy to energy.
