Enter the mass of the object and the upward acceleration into the calculator to determine the upward force.

Upward Force Formula

The following equation is used to calculate the Upward Force.

UF = m * au
  • Where UF is the upward force (N)
  • m is the mass (kg)
  • au is the upward acceleration (m/s^2)

To calculate an upward force, multiply the upward acceleration by the object’s mass.

What is an Upward Force?


An upward force measures the total force acting on an object in the vertical direction. This is typically determined by subtracting the total upward force by the total force due to gravity.

How to Calculate Upward Force?

Example Problem:

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

First, determine the mass. In this example, the mass is found to be 17 kg.

Next, determine the upward acceleration. In this case, the upward acceleration is measured to be 4 m/s^2.

Finally, calculate the Upward Force using the formula above:

UF = m * au

UF = 17 * 4

UF = 68N
