🔵 Part 1: Multiple Choice

Circle the best answer for each question.

1. What is a force?

A type of energy stored inside an object

A push or a pull acting on an object

The weight of an object in kilograms

The speed at which an object moves

2. Which of the following is an example of a contact force?

Gravity pulling a ball to the ground

A magnet attracting a paperclip from a distance

Friction between a shoe and the floor

The Earth pulling the Moon into orbit

3. What is the unit used to measure force?

Kilogram (kg)

Newton (N)

Metre (m)

Joule (J)

4. When two forces acting on an object are equal in size but opposite in direction, the forces are called:

Unbalanced forces

Gravity forces

Balanced forces

Friction forces

5. A skydiver opens their parachute and slows down. Which force increased to cause this?

Gravity

Air resistance (drag)

Magnetism

Tension

✅ Part 2: True or False

Write True or False on the line next to each statement.

6. Gravity is a non-contact force that pulls objects towards each other. _____________

7. Friction always speeds objects up. _____________

8. An object will remain still or keep moving at the same speed if the forces acting on it are balanced. _____________

9. Weight and mass are exactly the same thing. _____________

✏️ Part 3: Short Answer

Answer each question using full sentences where possible.

10. Name two types of non-contact forces and give one real-life example of each.

11. A shopping trolley is sitting still in a car park. A person pushes it with a force of 30 N to the right. Describe what will happen to the trolley and explain why using the idea of balanced and unbalanced forces.

12. Look at the diagram description below and answer the question.

A box is being pushed to the right with a force of 50 N. Friction acts to the left with a force of 20 N.

What is the net (total) force on the box, and in which direction will it move? Show your working.

Part 1: Multiple Choice

1. B — A push or a pull acting on an object

2. C — Friction between a shoe and the floor

3. B — Newton (N)

4. C — Balanced forces

5. B — Air resistance (drag)

Part 2: True or False

6. True

7. False — Friction slows objects down

8. True

9. False — Mass is the amount of matter in an object (measured in kg); weight is the force of gravity acting on that mass (measured in Newtons)

Part 3: Short Answer

10. Accept any two from: Gravity (e.g. Earth pulling a falling apple), Magnetism (e.g. a magnet attracting iron filings), Electrostatic force (e.g. a balloon sticking to a wall after rubbing).

11. The trolley will start moving to the right. Before the push, forces were balanced (gravity down, ground reaction up, no sideways force). The 30 N push creates an unbalanced force, so the trolley accelerates in the direction of the push.

12. Net force = 50 N − 20 N = 30 N to the right. The box will move to the right because the forces are unbalanced — the pushing force is greater than friction.

💡 Relief Teacher Tip: If students finish early, ask them to sketch a force diagram (arrows showing direction and size) for Question 12. This reinforces the concept without needing any extra materials.
