📚 Part 1: Work Formula Review

1. The formula for calculating work is:

W = F ÷ d

W = F × d

W = F + d

W = F - d

2. In the work formula, what does "d" represent?

Distance traveled in the direction of the force

Density of the object

Diameter of the object

Direction of the force

3. The unit for work is:

Newtons (N)

Meters (m)

Joules (J)

Watts (W)

🔢 Part 2: Work Calculations

4. A student pushes a box with a force of 25 N for a distance of 8 feet. Calculate the work done.

Work = _________ J

5. A worker lifts a 40 N toolbox vertically upward 3 feet. How much work is done against gravity?

Work = _________ J

6. If 150 J of work is done by applying a 30 N force, what distance was the object moved?

Distance = _________ feet

7. A car engine does 2,400 J of work to move the car 20 feet. What force did the engine apply?

Force = _________ N

💭 Part 3: Real-World Applications

8. Maria carries her 15 N backpack horizontally for 100 feet across the school hallway. How much work does she do on the backpack? Explain your answer.

9. Give an example from your daily life where you do work (in the physics sense). Identify the force, distance, and calculate an estimated amount of work done.
