What is Δp Δt?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Δp/Δt equals average force according to Newton's second law:
- Δp = change in momentum (kg·m/s)
- Δt = time interval (s)
- F_avg = Δp/Δt
This represents how quickly momentum changes. Alternative form: F = dp/dt (instantaneous force as rate of momentum change).
