Question

Differentiate between mass and wieght, at least 3 point.​

Answer 1

The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it.

↘Definition:-

♠Mass is simply the measure of the amount of matter in a body.

♣Weight is the measure of the amount of force acting on a mass due to acceleration due to gravity.

↘ Denotation

♠Mass is denoted by “M”.

♣Weight is denoted by “W”.

↘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

↘Quantity Type

♠Mass is a base quantity.

Mass only has magnitude and so, it is a scalar quantity.

♣Weight is a derived quantity.

Weight has both magnitude and direction (towards the centre of gravity) and so, it is a vector quantity.

↘Unit of Measurement

♠The SI unit of mass is Kilogram (Kg).

♣The SI unit of weight is Newton (N).
