How to calculate W in physics?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Calculating work (W) in physics:
- Identify all forces acting on the object
- Measure displacement in the direction of motion
- Determine the angle between force and displacement
- Apply formula: W = F × d × cos(θ)
- Consider sign: Positive if force aids motion, negative if opposes
For variable forces, use integration: W = ∫F(x)dx over the displacement range.
