Forces and Motion Introduction

Forces and motion illustration

📚 Part 1: Understanding Forces

1. What is a force?

A type of energy

A push or pull that can change motion

The speed of an object

The weight of an object

2. Which of the following are examples of contact forces? (Check all that apply)

Pushing a shopping cart

Gravity pulling an apple down

Friction from car brakes

A magnet attracting a paperclip

Pulling a rope

3. Which force is acting on a ball when you drop it from your hand?

Friction

Gravity

Tension

Applied force

4. The main difference between contact and non-contact forces is:

Contact forces are stronger

Non-contact forces only work in space

Contact forces require objects to touch, non-contact forces don't

Contact forces are always pushing forces

✏️ Part 2: Identifying Forces in Action

5. Look at the toy car activity from class. Name one contact force and one non-contact force that acted on the car:

Contact force: _________________________________

Non-contact force: _________________________________

6. Explain how the ramp affected the motion of the toy car. What force was responsible?
7. Complete the sentences using the words: gravity, friction, applied, magnetic

a) When you push a book across a table, you are using an _____________ force.

b) The force that makes a paperclip stick to a refrigerator is _____________ force.

c) The force that pulls objects toward Earth is _____________.

d) The force that slows down a sliding object is _____________.

8. Describe a real-world example where you can observe both a contact force and a non-contact force working on the same object:

🔬 Part 3: Thinking Like a Scientist

9. During our group activity, what happened to the car's motion when different forces were applied? Give two specific examples:

Example 1: When we ________________________________,

the car _________________________________________________.

Example 2: When we ________________________________,

the car _________________________________________________.

10. Based on what you learned today, predict what might happen if all forces acting on a moving car were perfectly balanced. Explain your thinking:
