  • Solution

  • Transcript

Solution:

Mass

  1. It is constant for a body and it does not change by changing the place of the body
  2. S.I unit is kilogram
  3. It is the quantity of matter of a body

Weight

  1. It is not constant for a body,but it changes from place to place
  2. It is measured by a spring balance
  3. S.I unit is newton (N)

hello welcome to Lido homework today we are going to see the differences between the mass and weight let's do it what is the difference between the mass and weight so what the mass means okay so let's find out what is the mass means mass here first the steps of mass and we write down here first one is mass different it's it's constant for a body and does not change by changing the place it's going to be constant okay it's going to be constant and the second one the second is acid is kilogram s I unit is kilogram next one-third point you could take it as this is the quantity of matter of the body it is quantity of matter of the body okay these are the things of the mass and let's look into the next one that is weight what is the weight and how it is not constant the first point is the same opposite of it not constant in all the places okay the second point take it as it is measured by spring balance it can be it can be measured measured by spring balance can be measured measured by a spring balance okay that's it so it's the quantity of matter of the body and it is a sign it is going to be newton's newtons is going to be the units of it what what is this it is going to be the si unit okay so I have to understand what is the mass and what is the weight means I hope you understood this video subscribe to the channel for regular updates and thanks for watching this video
