Enter the total force and the elapsed time into the calculator to determine the Momentum from Force. 

Momentum from Force Formula

The following equation is used to calculate the Momentum from Force.

p = TF * dT
  • Where p is the Momentum from Force (m/s*kg)
  • TF is the total force (N)
  • dT is the elapsed time (s)

To convert force to momentum, multiply the force by the change in time.

What are the units for Momentum from Force?

The most common units for Momentum from Force are m/s*kg.

How to Calculate Momentum from Force?

Example Problem:

The following example problem outlines the steps and information needed to calculate the Momentum from Force.

First, determine the total force. In this example, the total force is determined to be 40 (N).

Next, determine the elapsed time. For this problem, the elapsed time is measured to be 30 (s).

Finally, calculate the Momentum from Force using the formula above: 

p = TF * dT

Inserting the values from above and solving the equation with the imputed values gives: 

p = 40 * 30 = 1200 (m/s*kg)
