Question

twodifferencesbetweenmassandweight

Answer 1

━━━━━━━━━━━━━━━━━━━━━━━━━

1) Mass is a measurement of the amount of matter something contains, while Weight is the measurement of the pull of gravity on an object. 2) Mass is measured by using a balance comparing a known amount of matter to an unknown amount of matter. Weight is measured on a scale.

Answer 2

Explanation:Difference Between Mass and Weight

1.) Definition- Mass is simply the measure of the amount of matter in a body, whereas Weight is the measure of the amount of force acting on a mass due to acceleration due to gravity.

2.) Denotation-Mass is denoted by “M”while Weight is denoted by “W”.

3.) Formula- Mass is always constant for a body and there are several formulas to calculate mass. One way to calculate mass is:

Mass = volume × density

Weight is the measure of the gravitational force acting on a body.

Weight can be calculated from the following formula:

Weight = mass × acceleration due to gravity

4.) Quantity Type-Mass is a base quantity. Mass only has magnitude and so, it is a scalar quantity.  whereas Weight is a derived quantity. Weight has both magnitude and direction (towards the centre of gravity) and so, it is a vector quantity.

5.) Unit of Measurement- The SI unit of mass is Kilogram (Kg),and

The SI unit of weight is Newton (N).

6.) Gravitational Effect-Mass does not depend upon gravity and is constant everywhere. Mass can never be zero,while  Weight is dependent on the gravity and so, it varies from place to place. Weight can be zero where there is no gravity (like space).

7.) Measuring Instrument-Mass can be easily measured using any ordinary balance like beam balance, lever balance, pan balance, etc.

Weight can be measured by a spring balance or by using its formula.
