so they have been chosen according to what conventions

then the 7 fundamental physical quantities that we read are they incorrect ?

L=Velocity x time here length is directly proportional to time so come is it independent as it should be since it's a fundamental...

yeah i see it so can you provide the correct expression please

sorry for a late reply but, just one question is the following expression correct for average velocity in plane polar coordinate system?

can you give an example for me to better understand

so how can we express something like avg. velocity in a coordinate system like plane polar coordinate system where the unit vectors are...

using the law of cosine we can say that the third side will be equal to [2(1-cos theta)]^1/2 but also what will be the direction of the...

by the way how did we get that expression for the magnitude of the change in the unit vector

there can't be any change in the magnitude of a unit vector right??? so how come it's equal to 2sin(wt/2)

so can we write delta r hat and delta theta hat as delta theta/ delta t cause a change in them can be only due a change in angle since...

so what will they be

but what about 2-d motions other than circular motion

so if we could find a way to express the avg. change in unit vectors then the problem would be sorted right??

in the case of circular motion the r hat component of the velocity is anyways 0 since there is no displacement along that component and...
