🎯 WALT: Recognise different forces and explain how they affect motion

📚 Part 1: Multiple Choice

1. What is gravitational force?

A force that pushes objects away from Earth

A force that attracts objects towards Earth

A force that only works on heavy objects

A force that stops all motion

2. Frictional force acts:

Only on moving objects

Between surfaces in contact

Only in the same direction as motion

Only on rough surfaces

3. Which surfaces would create the MOST friction on a sliding block?

Smooth tile

Polished metal

Rough sandpaper

Wet glass

4. When you push a toy car across the floor and it slows down, which force is mainly responsible?

Gravity pulling it down

Friction opposing its motion

Air pushing it backwards

Magnetism from the floor

✏️ Part 2: Investigation Analysis

5. You tested a block sliding on three different surfaces and got these results:

Smooth tile: 85 cm | Carpet: 45 cm | Sandpaper: 25 cm

a) What pattern do you observe in the data?

b) Explain this pattern using your knowledge of friction:

6. Complete this sentence using scientific language:

Gravity always acts _____________ on objects, while friction acts _____________ to the direction of motion and tends to _____________ moving objects.

7. Draw and label a simple diagram showing the forces acting on a book sliding across a desk:

🚀 Part 3: Application and Extension

8. Support Prompt: Use these sentence starters to explain why a ball rolls further on a basketball court than on grass:

The ball rolls further on the court because...

Friction on grass is...

This shows that friction...

9. Real-life Application: A cyclist is riding down a hill. Identify TWO forces acting on the cyclist and bicycle, and explain how each affects their motion:

10. Extension Challenge: Design a quick investigation to test how push strength affects distance travelled (keeping surface type the same). Include your prediction and one variable you would control:

Success Criteria Check: Can you tick what you've achieved today?

I can name and explain gravitational force

I can name and explain frictional force

I can describe how surface roughness affects motion

I can show forces acting on objects using diagrams or descriptions
