Which statement about energy is true?

• Energy can be destroyed.

• Energy can be created.

• Energy cannot change form.

• Energy cannot be created or destroyed, but its form can change.

Answer explanation

The correct statement about energy is 'Energy cannot be created or destroyed, but its form can change.' This principle is known as the law of conservation of energy. It states that energy can only be transformed from one form into another, but it can't be created or annihilated.

he diagram below represents energy transformations in a moving electric toy car. Which form of energy is the original source of power for this car?

• electrical

• mechanical

• sound

• light

Answer explanation

The original source of power for this car comes from the light from the sun being captured by the solar panels and producing electrical energy for the motor to run and the car to move.

Which choice best describes kinetic energy?

• energy of motion

• energy of nutrition

• energy of objects

• the total energy of an object

Answer explanation

Kinetic energy is best described as the energy of motion. This means that any object that is in motion has kinetic energy. The option 'energy of motion' clearly defines this concept, making it the correct choice. The other options do not accurately define kinetic energy.

In the picture, a man has lit a match.

Which of the following shows the sequence of energy transformations taking place?

• light → chemical → heat

• heat → electrical → light

• chemical → electrical → heat

• chemical → heat → light

Answer explanation

In the given question, the energy transformation happening when a man lights a match is as follows: chemical energy in the match is first converted into heat energy due to the friction, which then radiates as light energy.
