Momentum and Impulse Calculator
Enter an object’s mass and velocity to calculate momentum, or add a force and time to calculate impulse and velocity change.
Momentum and Impulse Calculator
Calculate momentum, impulse, and the resulting change in velocity from a force applied over time.
Momentum describes an object’s mass in motion, while impulse — a force applied over time — describes a change in that momentum. This calculator computes both, along with the resulting velocity change from the impulse-momentum theorem.
Example
- With the default values shown above, this calculator returns: Initial Momentum ≈ 20.00; Impulse ≈ 20.00; Resulting Change in Velocity ≈ 4.00; Final Velocity ≈ 8.00.
Frequently Asked Questions
What is the impulse-momentum theorem?
It states that the impulse applied to an object (force × time) equals the change in that object’s momentum — this calculator uses that relationship to find the resulting change in velocity.
What are the units of momentum and impulse?
Momentum is measured in kilogram-meters per second (kg·m/s), and impulse is measured in newton-seconds (N·s) — these two units are dimensionally equivalent.
