Settings

Work is calculated from the selected mode; power uses the same work divided by time.
Quick summary
Select a mode, enter values, and (optionally) time to get power.

Enter values

Direction matters: sign depends on θ and input signs.
Displacement can be negative (direction).
θ is between force and displacement. 90° → 0 work.
If time is empty, we show work only. If time ≤ 0, power is invalid.
