Results
Work in joules (J).
500
Explanation note.
功 = F·d·cosθ = 50×10×cos(0°) = 500 J。
At a glance:Work W = F·s·cosθ is the energy transferred by a force acting through a displacement. Only the component along the displacement counts; at 90° no work is done. θ=0 → W=F·s. Units: joules (J = N·m).
Formula
W = F·s·cosθ
F = W/(s·cosθ) ; s = W/(F·cosθ)
How to Use
- Enter force F, displacement s and angle θ.
- The tool gives the work W.
Case Studies
10 N over 5 m, theta=0 deg
W = 10 × 5 × cos0 = 50 J.
FAQ
θ=90°?
Zero work.
Negative work?
When force opposes motion (cosθ<0).
Versus energy?
Work is a transfer of energy.
