Enter the spring constant, the displacement, and the time of spring force into the calculator to determine the Spring Momentum. 

Spring Momentum Formula

The following equation is used to calculate the Spring Momentum.

pS = K*x *t
  • Where ps is the Spring Momentum (m/s*kg)
  • k is the spring constant (N/m)
  • x is the displacement (m)
  • t is the time of spring force (s)

To calculate the spring momentum, multiply the spring constant by the displacement and time.

What are the units for Spring Momentum?

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

How to Calculate Spring Momentum?

Example Problem:

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

First, determine the spring constant. In this example, the spring constant is determined to be 50 (N/m).

Next, determine the displacement. For this problem, the displacement is measured to be 3 (m).

Next, determine the time of spring force. In this case, the time of spring force is found to be .123 (s).

Finally, calculate the Spring Momentum using the formula above: 

pS = K*x *t

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

pS = 50*3 *.123= 18.45 (m/s*kg)
