Quest into arena of Classical mechanics

[ARPAN]

this thread is intended to be an open discussion on classical mechanics in question answer format ( as i mentioned in the very beginning) rather than ur silly perception.
its all about an in-depth information on the subject of classical mechanics.

moreover the calculus problem was intended to test members proficiency in it rather than challenge them and if u wanna take it that way remember that science is nothing but a serious challenge to discover the unknown

and as for ur further queries there is no point in checking ur knowledge for me.
the problems posted here are intended to test ur comprehensive and reasoning ability and at the same time present the fundamentals of the subject in a lucid way.

if u think u r a genius in the subject try refining ur skills

the answer to the problem of Foucault pendulum and N-block system will be provided in the next 24 hrs if no one is able to approach it

try reading the question on Foucault pendulum once again . the answer is hidden in the question.

answer for first part of N-block system is

F - F (m1 + m2+m3+......+mn)/ (m1+m2+m3+..........+mN)

members may visit the chemistry section for the topic fundamentals of chemistry posted by me

go through it and provide suggestions.

I have a question.. why isnt angular displacement (like linear displacement) a vector?
Why is angle a scalar but the differential angle a vector?

[ARPAN]

@alphavictor

angular displacement is not regarded as a vector for small displacements...

for better clarity
consider a man walking in unidirectional motion for negligible distance

for more details, post me via g.v.

[alphavictor]

lets talk in general about normal angular displacements...

[ARPAN]

In three dimensions, angular displacement has a direction and a magnitude. The direction specifies the axis of rotation; the magnitude specifies the rotation in radians about that axis (using the right-hand rule to determine direction). Despite having direction and magnitude, angular displacement is not a vector because it does not obey the commutative law.
