📚 Part 1: Understanding Forces

1. What is drag?

A force that speeds up objects

A force that slows down objects moving through air or water

A force that makes objects float

A force that pulls objects downwards

2. What is upthrust?

A force that pulls objects down in water

A force that pushes objects up when they are in water

A force that makes objects move faster

A force that stops objects from moving

3. Which of these situations show drag forces? (Tick all that apply)

A cyclist feeling wind resistance

A paper plane slowing down in the air

A boat floating on water

Swimming through water

4. A paper plane with bigger wings will experience _______ drag than one with smaller wings.

more

less

the same

🔬 Part 2: Experiment Results

5. Complete this table with your experiment results:

Objects tested in water:

Object 1: _________________ | Float/Sink: _________

Object 2: _________________ | Float/Sink: _________

Object 3: _________________ | Float/Sink: _________

6. Which object moved through water the slowest? Why do you think this happened?

7. Explain in your own words why boats can float on water.

8. A cyclist crouches down low on their bike to reduce _______ force, which helps them go _______.

Fill in the blanks: _____________ and _____________

🎯 Part 3: Apply Your Knowledge

9. Draw and label a diagram showing the forces acting on a floating boat. Include arrows to show the direction of each force.

10. Predict what would happen if you dropped a feather and a stone at the same time. Explain your prediction using what you know about drag forces.

11. Design a simple experiment to test which shape experiences more drag in air. Describe your method in 3 steps:
