Impulse and Momentum Calculator

Impulse equals the change in momentum of an object. It can be calculated from the force applied over a time interval, or directly from mass and velocity change.

What Is the Impulse and Momentum Calculator?

Impulse is the change in momentum produced when a force acts for a time: J = FΔt = mΔv.

How Does the Impulse and Momentum Calculator Work?

For a constant force: J = F × Δt. For known mass and velocity change: J = m × Δv.

Impulse and Momentum Calculator Formula & Variables

The core mathematical equation utilized by this calculator is expressed as:

J=FΔt=mΔvJ = F\Delta t = m\Delta v

The impulse-momentum theorem: impulse equals the change in momentum. Units: N·s = kg·m/s.

How to Use the Impulse and Momentum Calculator

  1. Choose force-time or mass-velocity method and enter the values.

Step-by-Step Example Calculation

500 N for 0.1 s

Input Values:

mode:forceTime
force:500
time:0.1
Worked Steps: J = 500 × 0.1 = 50 N·s.

Understanding Your Result

Larger force or longer contact time = larger impulse = greater momentum change.

Factors That Affect the Result

  • Airbags increase contact time, reducing peak force while delivering the same impulse.

When Should You Use This Calculator?

  • Car crash analysis, sports science (hitting a ball), rocket propulsion.

Assumptions & Limitations

  • Assumes constant force for the J = FΔt formula.
