How to calculate
Find impulse and momentum change from average force over a time interval.
Impulse = f*t N·s; Momentum change = f*t kg·m/s
Worked example
Average force (N): 100; Time interval (s): 0.2.
Impulse: 20 N·s; Momentum change: 20 kg·m/s.
Assumptions and limits
The force component must use the same axis as the desired momentum change. For changing force, enter its actual time average.
