Power — the rate at which work is done.
Formulas:
- Instantaneous power: P = dW/dt
- Average power: P_avg = ΔW/Δt
- For a point particle under force F and velocity v: P = F · v = F v cosθ (θ is angle between F and v)
- For rotation: P = τ ω (torque × angular speed)
Units: watts (W) = joules per second (J/s).
