00:00Hello dear friends and students welcome to my youtube channel dear friends today we will
00:14learn about the difference between mass and weight so let's start first of all how can
00:28we define mass is mass is the quantity of matter present in any substance
00:58means the quantity of matter present in any substance is known as mass and how can we define weight it is a force means it is a type of force with which
01:21bodies or objects are attracted towards the center of earth
01:48or we can also say as surface of earth means mass is the quantity of matter present in any substance and weight is a force with which bodies are attracted towards the center of earth
02:07the second difference is it is denoted by m mass is denoted by m and weight it is denoted
02:33by w the third one difference is it is a scalar quantity means mass is a scalar quantity it
02:57doesn't possess any direction it is a vector quantity as weight is a vector
03:16quantity and is directed towards the center of earth as weight is a vector quantity and
03:42directed towards the center of earth mass is calculated by using formula m is equal
03:58to f upon a or m is equal to w upon g and weight is calculated by using formula w is
04:20equal to mg means mass into acceleration due to gravity is mass is constant everywhere
04:47take a suppose a body of 5 kg is taken to the surface of moon then its mass will remain 5 kg
04:57there will be no effect on its mass but weight is a variable quantity
05:24and it depends upon value of g means acceleration due to gravity if the mass of body is 5 kg then
05:51its weight on the surface of earth will be 5 into 10 we will take the value of g as 10 so it will
06:02be 50 Newton if we will take this body on the surface of moon then its weight will become as
06:12m into g mass is 5 kg and g on the surface of moon is 1.6 so it will be 8 Newton from this we
06:27observed that the weight of a body changes from one point to n other points but mass remains
06:35constant are same everywhere the SI unit of mass
06:45is kilogram and the SI unit of weight
07:05is Newton
07:18CGS unit of mass is gram
07:29CGS unit of weight is dime FPS unit of mass is
07:44salug and FPS units of weight is pound which is denoted by the symbol LB means
08:03Libra is mass is measured by using physical balance and weight is measured by using a spring
08:26balance so dear students that was about the difference between mass and weight thank you
