differebce between maas and weight
Answers
the difference between the mass and weight is
mass the total volume it takes in the earth
weight the force by which it is pull by earth
Answer:
hope it is clear to you please mark as brilliant answer
Explanation:
Since you say that you have read the definitions in books, lets refer to them :
Mass remains same everywhere and weight changes. What does that exactly mean? Lets say you are made up of atoms and particles whose quantity can be measured as 'mass'. You will always be made up of this same amount of matter(unless you're on a diet,of course) or particles wherever you go. This amount of substance that makes 'you' is called mass and be it earth,moon, jupiter you are 'you' i.e. you don't change which means the amount of stuff that makes 'you' doesn't change and hence your mass doesn't change and is the same everywhere.
Lets understand weight. Weight is not a measure of amount of substance. It is a Force. Understand force : if you pull a person towards you softly, they may not move or may move slowly towards you. However if you pull forcefully (apply more force), they will get dragged immediately towards you because they were acted upon by more force. Lets measure this in KG. Lets say when you pull softly the force you apply is very little,say 2KG and when you pull strongly, you apply a force of 20KG. All the while that person does not change, they are still made up of same amount of particles/matter in both cases which is their 'mass'. Thus you are pulling the same mass in both cases and this mass can have different weights(2kg or 20kg) according to how much force it is pulled with.
Now replace the person who is doing the pulling, with planets and stars. All planets and stars pull 'mass' with a force called 'gravity'. This gravity depends on how much mass that object is having. Just like a bigger guy(more mass) can pull with more force than a smaller guy(less mass), similarly bigger objects(Sun,Jupiter) can pull with more force than smaller ones(Earth, moon). This capability of pulling is called that object's gravity. Earth pulls you with a force of (your mass) x 9.8(acceleration due to gravity). Similarly when you go to different planets or stars, all will pull you with a different amount of force which will be called your weight at that place, however your mass will not change.
In the below example, there is an astronaut on earth and on the moon. The Moon's gravity is much less than the Earth's gravity - approximately one sixth. So, a 100 kg mass astronaut weighs 980N on Earth. On the Moon, the astronaut would weigh only 162.2N. However, the astronaut's mass is 100kg where-ever they are.
Weight on Earth: mass x acceleration of earth = 100kg x 9.8m/s2 = 980N.
Weight on Moon: mass x acceleration of moon = 100kg x 1.622 m/s2 = 162.2N.
