Mass Weight Density Quiz

shape Introduction

Mass Weight Densityis an important topic in General Science. Mass Weight and Density Quiz article, is exceedingly important for candidates preparing for RRB ALP/Technical Exams/Junior Engineer Recruitment Exams. In this article, candidates can find different types of questions with solution related to the Mass Weight Density topic. The article Mass Weight Density Quiz, will assist the students understanding of the type of questions expected from the topic Mass, Weight and Density.
Mass is both a property of a physical body and a measure of its resistance to acceleration (a change in its state of motion) when a net force is applied. The object’s mass also determines the strength of its gravitational attraction to other bodies. The basic SI unit of mass is the kilogram (kg).
In science and engineering, the weight of an object is related to the amount of force acting on the object, either due to gravity or to a reaction force that holds it in place.
The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume. The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume.
