What Is the Difference Between Weight and Mass.docx

1. What Is the Difference Between Weight and Mass ? We often use Weight and Mass interchangeably which creates confusion in understanding the difference between these two values. Students often find mass and weight to be the same thing, however, it is really different and has their own importance in the history of Science. MASS: Mass is the amount of matter present in an object or a substance. The standard unit (SI) of mass is Kilogram (Kg). However, smaller masses use units milligram (g). The mass stays the same everywhere, whether it is placed on the Earth or Moon or any other planet. For instance, if the mass of a specific object is 50Kg on Earth then even if it is placed on the Moon it will stay constant. Mass is

Formulas to calculate the mass are the following: Mass = Density (ρ) x Volume (V) Mass = ρxV Gravitational acceleration (g) Mass = Weight (W) Mass = W/g Acceleration (a) Mass = Force (F) Mass = F/a One of the important things about mass is that it can never be zero (0) and since it is constant everywhere it does not depend on gravity. There are many ways to measure mass of an object and some of them are through using ordinary balance. For instance, in scientific experiments, labs etc, balances lik e an electronic balance, double pan balance, lever balance, and triple beam balance etc. Mass is a base quantity. Moreover, Mass is a scalar quantity since it has only magnitude unlike Weight. Related Read: https://mytutorsource.com/blog/how-mts-tutors-can-help-you-in- improving-your-mathematics/ WEIGHT:

3. Weight of an object is the measure of the gravitational pull on an object. The standard unit (SI) of weight is Newton (N). Unlike mass, weight does not stay the same anywhere, whether an object is placed on the Earth or Moon or any other planet. For instance, if the weight of a specific object or a person is 490 N (50kg) on Earth then if it is placed on Mars it will change because of the gravity being 3.7 there, and the weight will become 185 N solely because of the change in gravitational pull on the moon. Weight is denoted by ‘ W ’. There are many ways to calculate the weight of an object or a person. One of the important formulas to calculate the weight of an object is: Weight = Mass (m) x Acceleration (a) MASS WEIGHT ‘the amount or measure of matter present in an object or a substance’ ‘the measure of the gravitational pull on an object’ Standard unit (SI) of weight is Newton (N) Standard unit (SI) of mass is Kilogram (Kg) Weight = Mass (m) x Acceleration (a) Mass = Weight (W) Gravitational acceleration (g) Weight = m x a Mass = W/g Weight = Mass (m) x Gravitational Mass = Force (F) Acceleration (a) acceleration (g) Mass = F/a Weight = m x g Weight of an object varies from one place to another and can be zero (0) since it depends on the gravity. Mass of an object is that it can never be zero (0) and since it is constant everywhere it does not depend on gravity.

4. Mass is a scalar quantity since it has only magnitude unlike Weight. Weight is a vector quantity since it has magnitude and direction both One of the ways to calculate the mass of an object is through using ordinary balance, for example, an electronic balance, double pan balance, and triple beam balance etc. One of the ways to calculate the weight is through using a hydraulic scale or a spring scale. Weight = m x a Weight = Mass (m) x Gravitational acceleration (g) Weight = m x g One of the important things about weight of an object is that it varies from one place to another and can be zero (0) since it depends on the gravity. There are many ways to measure weight of an object and one of them is through using a hydraulic scale or a spring scale. Moreover, Weight is a vector quantity since it has magnitude and direction both. Unlike Mass, weight is derived quantity.
