🔄 Part 1: Understanding Forces

1. What is a force? Circle the best answer:

A type of energy that makes things hot

A push or pull that can make things move or change shape

Something that only works with electricity

A tool used by scientists

2. Which of these are examples of forces? Check all that apply:

Opening a door

Pulling a drawer

Thinking about homework

Pushing a shopping trolley

Kicking a football

3. Fill in the blanks:

Forces can be divided into two main types: __________ and __________. When you use more force, objects can move __________ or travel a __________ distance.

📐 Part 2: Ramps and Motion

4. Look at the diagram below and predict what will happen. Draw arrows to show which ball will travel the furthest:

5. What happens when you make a ramp steeper? Circle the correct answer:

Objects move slower

Objects move faster

Nothing changes

Objects stop moving

6. Explain why you think the steepness of a ramp affects how objects move:

🏃 Part 3: Surfaces and Friction

7. Match each surface with how it affects motion:

1. Smooth plastic

2. Sandpaper

3. Carpet

4. Ice

A. Very slippery, little friction

B. Rough, lots of friction

C. Soft, medium friction

D. Slippery, low friction

8. What is friction?

A force that helps objects move faster

A force that slows down motion

A type of energy

Something that only happens on ramps

🎯 Part 4: Stored Energy and Rubber Bands

9. When you stretch a rubber band, what happens to the energy?

10. Predict what would happen if you stretched a rubber band more. Circle your prediction:

The object would travel a shorter distance

The object would travel a longer distance

Nothing would change

The rubber band would disappear

11. Draw a diagram showing how stretching a rubber band creates stored energy:

🔬 Part 5: Scientific Investigation

12. You want to test which surface makes a toy car travel the furthest. What would you need to keep the same to make it a fair test? Check all that apply:

Use the same toy car

Use the same starting height

Use different sized cars

Measure the distance each time

Change the ramp angle each time

13. Complete this prediction table:

Surface: Smooth plastic - Distance travelled: _______ metres

Surface: Sandpaper - Distance travelled: _______ metres

Surface: Carpet - Distance travelled: _______ metres

14. Explain why engineers need to understand forces and motion when designing products:
