Energy Concepts Worksheet

Explore how kinetic and potential energy differ. Use KE = ½ × m × v² for calculations. Show your working and include units in joules (J).

Choose the best answer

Select one answer for each question.

1.Which situation shows an object with kinetic energy?

A book resting on a desk
A scooter travelling along a footpath
A compressed spring held in place
A bucket of water on a high shelf

2.A stone is motionless on the edge of a high ledge. Which type of energy does it have mainly because of its position?

Sound energy
Gravitational potential energy
Kinetic energy
Electrical energy

3.Which expression is used to calculate the kinetic energy of an object?

KE = m × g × h
KE = ½ × m × v²
KE = m × v
KE = force × distance

4.A sled slides down a snowy slope. As it loses height and speeds up, which energy change happens mainly?

Kinetic energy changes into gravitational potential energy
Gravitational potential energy changes into kinetic energy
Kinetic energy changes into chemical energy
No energy changes form

Explain and complete

Use clear explanations. Energy is measured in joules (J), mass in kilograms (kg), and velocity in metres per second (m/s).

5.Explain the difference between kinetic energy and potential energy. Give one everyday example of each.

6.A ball is tossed straight upwards and then falls back down. Describe how its speed and its kinetic and gravitational potential energies change as it rises and falls. Ignore air resistance.

7.Complete each sentence using words from this bank: moving, stored, height, potential, joules. Kinetic energy belongs to objects.

8.Complete the sentence using words from this bank: moving, stored, height, potential, joules. Potential energy is energy.

9.Complete the sentence using words from this bank: moving, stored, height, potential, joules. Raising an object increases its gravitational energy.

10.Complete the sentence using words from this bank: moving, stored, height, potential, joules. The energy unit is .

Calculate kinetic energy

Use the kinetic energy equation. Substitute the mass and velocity, then give your answer in joules.

11.A 0.6 kg netball travels at 8 m/s. Calculate its kinetic energy.

Challenge

A small electric car has a mass of 900 kg. It slows down as its brakes are applied.

12.The 900 kg car is travelling at 18 m/s. Calculate its kinetic energy.

13.The same 900 kg car has slowed to 6 m/s. Calculate its kinetic energy at this speed.

14.For the 900 kg car, compare its kinetic energies at 18 m/s and 6 m/s. How much kinetic energy was reduced, and what happens to much of that energy during braking?
