Enter the mass and acceleration of an object and the reference force into the calculator to determine the relative force.

Relative Force Formula

The following equation is used to calculate the Relative Force.

RF = m*a / F

  • Where RF is the relative force (relative to F)
  • m is the mass (kg)
  • a is the acceleration (m/s^2)
  • F is the base force (point of reference)

What is a Relative Force?

Definition:

Relative force is a term that describes the magnitude of a force compared to the forces acting upon an object.

How to Calculate Relative Force?

Example Problem:

The following example outlines the steps and information needed to calculate Relative Force.

First, determine the mass. In this example, the mass of the object is 50 kg.

Next, determine the acceleration. In this case, the acceleration is 20 m/s^2.

Next, determine the reference force. The reference force for this example is 2000 N.

Finally, calculate the relative force using the formula above:

RF = m*a / F

RF = 50*20 / 2000

RF = .50
