📌 Understanding Work Done
Work done is the energy transferred when a force is applied to an object over a displacement. It is calculated using:
Work (W) = Force (F) × Displacement (d) × cos(θ)
The unit of work is **Joule (J)**.
📌 Examples of Work Done Calculation
| Force (N) | Displacement (m) | Angle (degrees) | Work Done (J) |
|---|---|---|---|
| 50 | 10 | 0 | 500 |
| 30 | 5 | 30 | 129.9 |
| 100 | 2 | 45 | 141.4 |
❓ FAQs
Q1: How do I calculate work done?
✅ Work done is calculated using **W = F × d × cos(θ)**, where F is force, d is displacement, and θ is the angle between force and displacement.
Q2: What are the SI units of work?
✅ Work is measured in **Joules (J)**, where 1 Joule equals 1 Newton-meter (N·m).
Q3: Can work be negative?
✅ Yes, work is negative when the force applied is opposite to the displacement direction, meaning energy is removed from the system.
Q4: How can I calculate force if work and displacement are known?
✅ If work done and displacement are known, force can be calculated as **F = W / (d × cos(θ))**.
Q5: What happens when force and displacement are perpendicular?
✅ If force and displacement are perpendicular, cos(90°) = 0, meaning no work is done.
