Q:

# How are mass and weight related to each other?

A:

Mass and weight are closely related because mass affects the weight of an object experiencing the effects of gravity. Weight is the measure of the force of gravity on an object's mass, while mass is the measure of how much matter there is in an object.

Know More

An object's weight is calculated as the mass of an object in kilograms multiplied by the acceleration of gravity exerted in meters per second squared. The resulting number is expressed in newtons, named for Newton's second law of motion. An object's mass is determined by comparing it to an object with a known mass on a balance. An object with a mass of 1 kilogram would weigh 9.8 newtons on Earth, yet it would weigh essentially nothing in space while still having a mass of 1 kilogram.

In physics, the tension on a suspended object said to be equal to the weight of the object plus or minus the mass of the object times the acceleration acting on it. In other words, this is the weight of the object plus or minus the force on it, depending on the direction in which the force is acting.

To get the mass of an object using a triple-beam balance, sum up the notch readings of the rear beam weight, middle beam weight and front beam weight. Each notch on the middle beam, rear beam and front beam represents 100-gram, 10-gram and 1-gram weight increments, respectively.

Density of any object is calculated by dividing the object's mass by its volume. Density is determined by the concentration of molecules in an object, so objects with a heavy mass in relation to a smaller volume have a higher density than objects with a lower concentration of molecules over a relatively large volume.
