Forces and Motion Investigation

Name:

Date:

🚗 Part 1: Understanding Forces

1. What is a force?

A push or pull that can change an object's motion

The speed of a moving object

The weight of an object

The distance an object travels

2. When forces acting on an object are unequal, what happens?

The object stays perfectly still

The object changes its motion (speeds up, slows down, or changes direction)

The object disappears

Nothing happens

3. Which of these are examples of forces? (Check all that apply)

Pushing a shopping cart

Friction from the ground

Gravity pulling objects down

The color of an object

4. Fill in the blank: When you push a toy car with 5 pounds of force and friction pulls back with 2 pounds of force, the unequal forces cause the car to _______________.

Answer: ________________________

📊 Part 2: Investigation Data and Analysis

5. Based on our ramp experiment, which required more force?

Starting the car moving (overcoming static friction)

Keeping the car moving (overcoming kinetic friction)

Both required exactly the same force

6. Record your group's data from the car and ramp investigation:

7. Describe the pattern you observed when the car moved down ramps of different slopes:

8. Explain how energy was transferred in our balloon rocket demonstration:

🌟 Part 3: Real-World Applications

9. Give two examples from everyday life where unequal forces cause motion:

Example 1: ________________________________

Example 2: ________________________________

10. Draw and label a diagram showing unequal forces acting on an object. Include arrows to show the direction and size of each force.

11. Predict what would happen if you rolled a ball across these different surfaces. Explain your reasoning:

Smooth ice: ________________________________

Rough carpet: ________________________________

Why are your predictions different? ________________________________
