Force From Height Formula

The following equation is used to calculate the .

F = m*g*h / d
  • Where F is the force from height (N)
  • m is the mass of the object (kg)
  • g is the acceleration due to gravity (m/s^2)
  • h is the height (m)
  • d is the distance of impact (m)

To calculate force from height, multiply the mass by the height and acceleration due to gravity, then divide by the impact distance.

What is a Force From Height?

Definition:

A force from height typically refers to the total impact force that acts on an object dropped from a certain height.

How to Calculate Force From Height?

Example Problem:

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

First, determine the mass of the object . In this example, the mass of the object is found to be 15 kg.

Next, determine the height. For this problem, the height is found to be 200m.

Next, determine the distance of impact. In this case, the distance of impact is measured to be 2m.

Finally, calculate the force from height using the formula above:

F = m*g*h / d

F = 15*9.81*200 / 2

F = 14,715 N
