What this calculator does
Calculate impulse, average force, or contact time from J = FΔt.
How it works
The calculator evaluates impulse J = average force F × time interval Δt. Inputs are checked before calculation, and invalid values such as zero denominators or out-of-range selections produce a clear error instead of a misleading result.
