How to calculate work?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
To calculate work, follow these steps:
- Identify the force applied (F) in newtons
- Measure the displacement (d) in meters
- Determine the angle (θ) between force and displacement
- Apply the formula: W = F × d × cos(θ)
- If force varies, use W = ∫F·ds (integral calculus)
For example, if a 10N force moves an object 5m in the same direction: W = 10 × 5 = 50 joules.
