Question

I know the answer but iam not pretty sure about it..so can you guys just make it go wild about this one !

Answer 1

Heya....

==== Ans ====

By assuming :-

It's lifted from the surface of the earth considering only the gravitational force of body and thus ...

Change in PE = G.m.M/2R

G= >> gravitational force

m=>> mass of considering body

M=>> mass of earth

R=>> radius of earth

Mass defined according to modern define :- it doesn't depend on the velocity it is invariant so...

p not equal to mup and mup not equal to MV ... so in fact momentum is faster in any line...

Thank you

Answer 2

hey

here is answer


when the object lifted from a certain height h to next level of height H such that H is bigger than h. then the mass will not increase actually this equation is for the relavistic phenomenon.

E= mc^2

here

E is energy

m is mass

c is speed of light


you can see its proof in attachment.


actually this equation shows the relavistic relationship between energy, mass and speed of light.


and newton law of gravitation.

GMm/r^2

here

G= gravitational constant ( values 6.67*10^-11 Nm^2/kg^2)

M is mass of planet

m is mass of object

r is distance of object.

here it is showed that gravitational force is responsible for the variation of weight of object not mass.

weight and mass are two different things.

so both equations are correct.


hope it helps

thanks
