📚 Part 1: Multiple Choice

1. What happens when balanced forces act on an object?

The object accelerates

The object remains stationary or moves at constant speed

The object changes direction

The object always stops moving

2. In a tug of war where both teams pull with equal force, the forces are:

Balanced

Unbalanced

Not acting on the rope

Only acting downwards

3. Which of the following are examples of unbalanced forces? (Select all that apply)

A car accelerating from a traffic light

A book sitting on a table

A football being kicked

A person walking at constant speed

4. When unbalanced forces act on an object, the object will move in the direction of:

The smaller force

The larger force (resultant force)

Both forces equally

Neither force

🎨 Part 2: Force Diagram Drawing

5. Draw a force diagram for a box being pushed to the right with 50N while friction acts to the left with 20N. Label all forces and indicate the direction of motion.

6. Draw a force diagram showing balanced forces acting on a stationary car. Include at least two pairs of forces.

7. A toy car is being pulled by two children in opposite directions. Child A pulls with 15N to the left, Child B pulls with 25N to the right. Draw the force diagram and show the resultant force.

✏️ Part 3: Analysis and Explanation

8. A cyclist is riding at a constant speed on a flat road. Explain whether the forces acting on the cyclist are balanced or unbalanced, and justify your answer.

9. Complete the following sentences about resultant forces:

When forces are balanced, the resultant force is _________ N.

When forces are unbalanced, there is a _________ force in the direction of the _________ force.

If a 30N force acts to the right and a 12N force acts to the left on the same object, the resultant force is _____ N to the _______.

10. Look at this scenario: A heavy box sits on the floor. Two people push it - one person pushes with 40N to the right, another person pushes with 40N to the left. Predict what will happen to the box and explain your reasoning using scientific vocabulary.

11. Give three real-life examples of situations where unbalanced forces cause motion. For each example, identify the forces involved.
