Let’s go step by step to understand and solve this.
We are given the formula:
W = F × d
This means:
Work = Force × Distance
From the image, we also learn:
- Work is done when a force causes an object to move a distance.
- Force is measured in Newtons (N)
- Distance is usually measured in meters (m)
- Work is measured in Joules (J) — though not written here, it’s standard.
- The formula can be rearranged if needed:
→ If you know Work and Distance, you can find Force:
F = W ÷ d
→ If you know Work and Force, you can find Distance:
d = W ÷ F
Also important:
- Energy can’t be made or destroyed — only changed from one kind to another.
- Work done can become kinetic energy, heat energy, etc.
Now, since there’s no specific numerical problem given in the image (like “calculate work if force is 5 N and distance is 3 m”), I think your task is to understand and remember these key ideas.
But let’s make sure — maybe you’re supposed to fill in blanks? Looking at the image again:
There are blank lines for:
- Name
- Date
- Class
And then big bold formulas with definitions around them.
So perhaps your homework is to study this sheet and be able to explain what each part means.
Let me break it down simply:
---
✔ W = F × d
This is the main equation. Multiply force by distance to get work.
Example:
If you push a box with 10 Newtons of force, and it moves 2 meters, then:
Work = 10 N × 2 m = 20 Joules
---
✔ d = distance
It says: “The distance travelled by the object when the force is acting on it.”
Also: “Distance is usually measured in meters (m)”
So if something doesn’t move, even if you push hard, no work is done! Because distance = 0 → Work = 0.
---
✔ F = force
Defined as: “Something that changes the motion of an object”
Measured in Newtons (N)
Force makes things start moving, stop moving, or change direction.
---
✔ W = work done
Defined as: “The energy that is used to make the object move”
Measured in... well, it doesn’t say, but it’s Joules (J). Remember that!
Also: “Work done can be converted to other types of energy such as kinetic energy, heat energy etc.”
And: “Energy can’t be made or destroyed — it can only be changed from one kind to another.” ← This is the Law of Conservation of Energy.

Since there’s no actual calculation question, I’ll assume your job is to understand and maybe write down what each symbol means.
But just in case — let’s do a quick practice example together:
👉 Suppose you lift a book upward with a force of 5 Newtons, and you lift it 2 meters high. How much work did you do?
Step 1: Use the formula → W = F × d
Step 2: Plug in numbers → W = 5 N × 2 m
Step 3: Calculate → W = 10 J
Answer: You did 10 Joules of work.
---
Final Answer:
The key formula is
W = F × d, where Work equals Force times Distance. Force is measured in Newtons, distance in meters, and work in Joules. No movement means no work done. Energy is conserved — it changes form but isn’t created or destroyed.
