User Guide

Use this calculator to determine the mass of an object in milligram, gram, ounce, pound, kilogram, stone or ton units, from the kinetic energy or work required to accelerate or decelerate an object, and its velocity.

Formula

The formula used by this calculator to determine the mass of an object from the kinetic energy and velocity is:

m = 2 · KE / v²

Symbols

• m = Mass of object
• KE = Kinetic Energy
• v = Velocity of object

Kinetic Energy (KE)

This is the kinetic energy of a moving object and represents the work done to accelerate it from rest, or decelerate it to rest.

Velocity (v)

This is the velocity or speed of the moving object.

Mass (m)

This is the total mass of the object.
