🔍 Part 1: Understanding Forces

1. What happens when two equal forces pull on an object in opposite directions?

The object moves toward the stronger force

The object stays still or moves at constant speed

The object spins in circles

The object moves faster and faster

2. Unbalanced forces cause an object to:

Stay perfectly still

Move at the same speed forever

Accelerate (speed up, slow down, or change direction)

Disappear

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

A book sitting on a table

A car speeding up from a red light

Two people pushing a box with equal force from opposite sides

A ball rolling down a hill

A picture hanging on the wall

4. When forces are balanced, energy transfer ____________ occur.

does

does not

sometimes does

always does

🚗 Part 2: Toy Car Investigation

5. During your toy car experiment, what happened when you pulled the car with equal force from both sides?

6. Explain why the car behaved this way using the terms "balanced forces" and "energy transfer":

7. When you pulled harder on one side than the other, the forces were _____________ and the car ____________.

Forces were: _________________ Car motion: _________________

8. Draw arrows to show the forces acting on each toy car. Make longer arrows for stronger forces.

Scenario A: Car not moving (balanced forces)

Scenario B: Car accelerating to the right (unbalanced forces)

🌟 Part 3: Real-World Applications

9. Describe a real-world situation where balanced forces keep an object from moving:

10. A spaceship in space fires thrusters with equal force in opposite directions. Predict what will happen and explain why:

11. Complete the pattern: When forces are balanced → ____________. When forces are unbalanced → ____________.

Balanced forces result in: _________________________________

Unbalanced forces result in: _________________________________
