🔍 Part 1: Identifying Forces

1. A ball is rolling down a ramp and gradually slowing down. Which two forces are acting on the ball?

Gravity and friction

Magnetism and applied force

Normal force and magnetism

Applied force and friction

2. Which force prevents you from falling through your chair when you sit down?

Gravity

Friction

Normal force

Applied force

3. A magnet picks up a paper clip without touching it. This demonstrates which type of force?

A force that only works when objects touch

A force that can act at a distance

A force that only works on heavy objects

A force that makes objects fall down

4. Check all the forces that are acting on a book sitting on a table:

Gravity pulling it down

Normal force pushing it up

Friction from the table surface

Applied force from someone pushing it

📝 Part 2: Force Analysis

5. Explain why a toy car moves faster down a smooth ramp compared to a rough, sandpaper-covered ramp.

6. Fill in the blanks with the correct force types:

When you push a heavy box across the floor, you apply an _____________ force. The box experiences _____________ from the floor that resists its movement. _____________ pulls the box toward the Earth, and the floor provides a _____________ force to support the box's weight.

7. A student drops a pencil. Describe the motion of the pencil and explain which force is responsible for this motion.

🎨 Part 3: Force Diagrams

8. Draw a simple force diagram showing the forces acting on a soccer ball as it rolls across grass. Label each force with arrows showing their direction.

9. Think of an object in your daily life that experiences at least three different forces. Name the object and list the three forces:

Object: _____________________

Force 1: _____________________

Force 2: _____________________

Force 3: _____________________

10. Predict what would happen if there was no friction between a car's tires and the road. Explain your reasoning.
