Mechanical Work Done at an Angle Calculator

Mechanical work W measures energy transferred when a constant force F displaces an object by distance d at angle θ relative to the direction of motion: W = F × d × cos(θ).

W = F × d × cos(θ)

Step-by-Step Calculation

01Canonical Law: W = F × d × cos(θ)

02Given Inputs (Base Units): F = 250 N, d = 10 m, θ (°) = 30

03Solve for W (Mechanical Work Done): W = 2,165.06 J

Mechanical work W measures energy transferred when a constant force F displaces an object by distance d at angle θ relative to the direction of motion: W = F × d × cos(θ).

Real-World Reference Values

Collinear Force (θ = 0°)cos(0°) = 1.000 → W = F × d

100% of force contributes to forward work

Frequently Asked Questions

Why does carrying a heavy load horizontally perform zero gravitational work?+

When walking on level ground, the upward lifting force is perpendicular (θ = 90°) to horizontal displacement, and cos(90°) = 0.

When is mechanical work negative?+

When a resistive force such as kinetic friction opposes motion (θ = 180°, cos(180°) = -1), work is negative and removes kinetic energy from the system.

How do I convert work W into mechanical power?+

Divide total work W (in Joules) by the elapsed time t (in seconds) to obtain power in Watts (P = W / t).
