Mass can also be defined as "stored energy in particles.".Weight has both magnitude and direction it is a vector quantity.Mass only has magnitude, hence, it is a scalar quantity. Velocity of Electrons: Newtonian: Einsteinian: Difference: Unit: m/sec.Now, let us look at some important facts related to mass:
Weight can be measured by a spring balance or by using its formula given above.ĭid you know that we have different weights on the earth, the moon, and in space? However, our mass is the same everywhere. Mass can be easily measured using any ordinary balance.įor example, beam balance, lever balance, pan balance, etc. Weight has both magnitude and direction (toward the center of gravity) and hence, it is a vector quantity.Mass only has magnitude and hence, it is a scalar quantity.Formula of weight: Weight = mass × acceleration due to gravity.Weight is the measure of the gravitational force acting on a mass.One way to calculate mass: Mass = volume × density.Weight is defined as the amount of force acting on the mass of an object because of acceleration due to gravity.
Mass is defined as the amount of matter in a substance The difference between mass and weight is shown in the table given below. However, mass and weight are two different terms and it is important to understand the difference between them. MUCalc is a networkable and/or stand-alone linac monitor unit (MU) calculator, medical physics educational software, and a quality. People often get confused between mass and weight and they end up using these two terms interchangeably. Dimensional analysis is the use of a set of units to establish the form of an equation, or more often, to check that the answer to a calculation as a guard.
