⚙️ Part 1: Multiple Choice

Circle the best answer for each question.

1. Which of the following is the correct definition of a force?

A push or pull that can change an object's motion, speed, or shape

The weight of an object measured in kilograms

The speed at which an object travels in a straight line

The energy stored inside a moving object

2. A book is sitting still on a table. Which statement best describes the forces acting on it?

There are no forces acting on the book

Only gravity is acting on the book

Gravity pulls the book down and the table pushes it up equally

The table pushes the book upward with a greater force than gravity

3. Which type of force slows down a ball rolling across a wooden floor?

Gravity

Friction

Magnetic force

Applied force

4. On Earth, gravity pulls objects downward with an acceleration of approximately:

5 m/s²

9.8 m/s²

15 m/s²

100 m/s²

5. Select ALL examples of a pull force. (Select all that apply)

A magnet attracting a paperclip

Kicking a football

Earth's gravity pulling a dropped apple downward

Pushing a shopping trolley forward

Stretching a rubber band

✏️ Part 2: Knowledge and Understanding

Answer each question using full sentences where required.

6. Complete the table by writing the correct force type and one real-life example for each description.

Description

The force that pulls all objects with mass toward each other

A force that opposes the motion between two surfaces in contact

A contact force applied directly to an object to move it away

A contact force applied to draw an object closer

Force Type & Example

Force: _____________ / Example: _____________

7. A soccer player kicks a ball across a grass field. The ball eventually stops. Using your knowledge of forces, explain why the ball slows down and stops. Mention at least two forces in your answer.

8. Define the term balanced forces and give one example from everyday life.

9. A skydiver jumps from a plane. Describe how the forces acting on the skydiver change from the moment they jump until they reach terminal velocity.

🔬 Part 3: Practical Application

Use your scientific understanding to respond to the following.

10. A student pushes two different boxes across the floor. Box A has a rough surface and Box B has a smooth surface. Both boxes have the same mass. Predict which box will be harder to push and explain why, using the concept of friction.

11. Draw and label a force diagram (free body diagram) for a book resting on a desk. Show the direction and name of each force acting on the book.

12. Reflection: Describe one situation from your own life where understanding forces has helped you (or could help you) make a decision or stay safe. Explain which force(s) are involved.
