Question

What do you think ? if there would no motion on the earth then we would not have mass ?

How far it is correct ? justify it

Answer 1

Mass is the quantity of a substance present on a body. So, mass is universally constant. There should not be any misconception that if there is no motion, there would not be any mass.

But, we know

F = ma

Or a ∞ 1/m

Which means that the greater the mass, lower the acceleration. Thus mass depends on acceleration.
If t = 1, then
ΔV ∞ 1/m
Thus, in unit time, change is velocity is inversely proportional to m.

So, we can conclude that motion of a body depends on mass. But, it is wrong fact that if there is no motion there will be no mass.

Answer 2

Heya....

===== Answer ======

Yeah, mass is a quantity of any object to come in existence,, and mass leads to motion ,, so everyone think that if there would be no motion so there would be no mass but this estimation is not true....

Let see how it is wrong ,,

We know that F = ma
a is inversely proportional to the 1/m
Where mass is greater than acceleration ,,

If E = 1 then
Then change in velocity is inversely proportional to the mass...

Here motion isn't depend on the mass...

So,, mass will be exist when there will be no motion..

Thank you
