Adjust force and contact duration without changing your main result.
Calculate your baseline first
Impulse measures the effect of a force acting over time. It equals average force multiplied by contact time and is also equal to the change in momentum.
One newton equals one kg·m/s². Multiplying by seconds gives kg·m/s, which is the unit of momentum.
Yes. A negative impulse means the momentum change points opposite to the direction defined as positive.
Results are generated locally in your browser using J = FΔt or J = Δp = m(vf − vi). The force-time method assumes the entered force represents the average net force over the selected interval. Results are educational estimates; verify signs, units and model assumptions for engineering, safety or professional work.
