Wat is the difference between mass and weight?/
A body is composed of atoms and molecules. Atoms and molecules are composed of electrons, protons, neutrons and a number of fundamental particals, We do not know exactly how many fundamental partciles exist, what is their nature, what they are composed of etc.
Finally we reach what is the least quantum of matter? It is a mind boggling question.
Now it is conceived that the fundamental particles are the condensed forms of energy and the quantum of energy is a `string` and this concept is known as `String Theory`
So mass is nothing but the amount of energy in the condesed form. Interesting...isnt it?
Again the problem remains, how to deal with different quantities of mass? then the concept of weight comes in. It is the amount of force generated by the gravity of Earth. Since the magnitude of the earth`s force ...more
but in physics weight is said be as force
so it is w= m*a or g
g is gravity or acc.
m is mass
n w is weight
but S.I unit for both is same
Weight is a vector quantity.
Mass is a scalar one and has no direction.
Mass is constant but weight is relative. Our mass will be same on moon or on earth but weight will differ depending upon the value of "g".
WEIGHT------->>MASS X ACCELERATION ( OR ) MASS OF A BODY X GRAVITATIONAL FORCE
