Impulse Calculator

Use J = FΔt to find impulse and momentum change, with an optional mass input to estimate velocity change.

Average force

Mass (optional)

—N·s impulse

—kg·m/s momentum change

—Δv for entered mass

—duration ms

—J = FΔt = Δp

These are idealized classical-physics calculations. Real systems can differ because of air resistance, friction, deformation, measurement uncertainty, non-constant forces, or other effects not included in the selected model.
