# Mass Weight and Density Quiz 2

#### Quiz Description

Here in this second quiz, we shall go even further into the study of Mass, Weight, and Density. These three are very much related as mass is used in calculations involving weight and density. This quiz is tailored towards the ability to measure the mass of a substance, measure the volume of a substance, calculate the weight of a body, as well as the volume of that body or any given fluid.

Mass is the amount of matter contained in a body. It could also be described to be in direct relationship with the inertia of a body (The reluctance of a body to change its velocity). On the other hand, weight can be defined to be the force that pulls a body towards the earth.

Density on the other hand could be defined as the mass per unit volume of a body or fluid, commonly measured in kilograms per cubic meter (kg/m^3).

This quiz among others is one of the other A-level physics quizzes made available for you. Do you want to fully understand the ideas behind mass, weight, and density? All you need to do is take the quiz and see how much you know and need to know. Good luck as you practice for your exams.
