Free Balanced and Unbalanced Forces Worksheet Collection - Free Printable

To solve the problem, we need to calculate the net force acting on each object and determine whether the forces are balanced or unbalanced. Let's go through each scenario step by step.

Example:

- Forces: \( 8 \, \text{N} \) (right), \( 2 \, \text{N} \) (left)
- Net force: \( 8 \, \text{N} - 2 \, \text{N} = 6 \, \text{N} \) (to the right)
- Result: Unbalanced

1. Book:

- Forces: \( 10 \, \text{N} \) (up), \( 10 \, \text{N} \) (down)
- Net force: \( 10 \, \text{N} - 10 \, \text{N} = 0 \, \text{N} \)
- Result: Balanced

2. Tennis Ball:

- Forces: \( 9 \, \text{N} \) (up), \( 4 \, \text{N} \) (down)
- Net force: \( 9 \, \text{N} - 4 \, \text{N} = 5 \, \text{N} \) (upward)
- Result: Unbalanced

3. Moving Object with Two Workers:

- Forces: \( 7 \, \text{N} \) (right), \( 5 \, \text{N} \) (left)
- Net force: \( 7 \, \text{N} - 5 \, \text{N} = 2 \, \text{N} \) (to the right)
- Result: Unbalanced

4. Lawn Mower:

- Forces: \( 20 \, \text{N} \) (right), \( 2 \, \text{N} \) (left)
- Net force: \( 20 \, \text{N} - 2 \, \text{N} = 18 \, \text{N} \) (to the right)
- Result: Unbalanced

5. Parachute:

- Forces: \( 5 \, \text{N} \) (up), \( 17 \, \text{N} \) (down)
- Net force: \( 17 \, \text{N} - 5 \, \text{N} = 12 \, \text{N} \) (downward)
- Result: Unbalanced

6. Soccer Players:

- Forces: \( 54 \, \text{N} \) (right), \( 37 \, \text{N} \) (left)
- Net force: \( 54 \, \text{N} - 37 \, \text{N} = 17 \, \text{N} \) (to the right)
- Result: Unbalanced

7. Weightlifting:

- Forces: \( 50 \, \text{N} \) (up, each hand), \( 100 \, \text{N} \) (down)
- Net force: \( 50 \, \text{N} + 50 \, \text{N} - 100 \, \text{N} = 0 \, \text{N} \)
- Result: Balanced

Final Answers:

1. Book:
- Net force: \( 0 \, \text{N} \)
- Balanced

2. Tennis Ball:
- Net force: \( 5 \, \text{N} \) (up)
- Unbalanced

3. Moving Object with Two Workers:
- Net force: \( 2 \, \text{N} \) (right)
- Unbalanced

4. Lawn Mower:
- Net force: \( 18 \, \text{N} \) (right)
- Unbalanced

5. Parachute:
- Net force: \( 12 \, \text{N} \) (down)
- Unbalanced

6. Soccer Players:
- Net force: \( 17 \, \text{N} \) (right)
- Unbalanced

7. Weightlifting:
- Net force: \( 0 \, \text{N} \)
- Balanced
