so r is a function in terms of variable mass right!? like when i say impulse is integration(f dt) so that means as time chnages the force changes ,soin inertia it means as mass changes!? the r changes!

and also why did he make it integration( x dm)/M it seems tome as as mass in changing, but mass is constant for this particles!and even don't we get the constants out of integrtion soit would be xcm=x* integration(dm)/M so it would be 1=1! and also in I=intefration(r^2 dm) why did he only change...

momentof inertia and center of mass! in book of serway : he says moment of inertia of a body is m(r^2).---->(1) is mass of the body and r is the distance of the body. but for a rigid body we will divide into particles of very small masses so i = E(Mi * (Ri)^2) E() is submission function to...

is it this hard i just want to know the velocity equation between body attracted to a point or another body!

any help ??

ofcourse y is not a constant value since the distance which is y decreases as the body moves towards the point

I have a body of 1kg of mass being acted on by a force of magnitude equal (10000/(y^2)) [where y is the distance between the body and a certain point] and this force is in the direction pointing to the point so depending on what mentioned above :- what i know is : f = a = (1000 0/(y^2))...
