Calculator Use

The Impulse Momentum Calculator uses the formula FΔt = mΔv, or force F multiplied by the change in time Δt equals mass m times the change in velocity Δv.

Calculate force F, change in time Δt, mass m, velocity change Δv, initial velocity v₁ or final velocity v₂. We also calculate impulse J (Δp) and provide it below the answer for all calculations.

Impulse-Momentum Formula

Where:

• F = applied force
• Δt = change in time
• m = mass
• Δv = change in velocity

In this calculator we use Δt as the time interval. Instead of entering initial time t₁ and final time t₂, just enter the elapsed time.

You may recognize the left side of the impulse-momentum equation from the impulse formula:

and the right side of the equation from the momentum formula:

Change in momentum can be written as:

As impulse is the change in momentum we get the impulse-momentum equation from the equality:

Calculations Using the Impulse Momentum Formula:

Use the impulse momentum equation to find force, elapsed time, mass, change in velocity, v₁, or v₂.
