At the bottom of the circular path the summation of weight and normal reaction is equal to zero??

No I'm not familiar with that method

I mean that the forces acting on the body are only its weight and the normal reaction of the support

What is the acceleration of a body (you can consider it as a particle) moving in a circular path placed in the vertical plane as it passes through the bottom of the path? (Provided that the body is under its weight and the path normal only).

Why radians are usually neglected in dimensional analysis?

Why the negative pole of a battery is said to be of higher potential? While if we a consider a DC battery of 12V (for instance) then we have Vpn=V (positive) -V (negative)=12V whish is a positive quantity, then we should conclude that Vp>Vn in contradiction to first statement! Please illustrate...

Ohhthanks for ur time and that sweet link

Well, if u can find that then please send me a link

This is mentioned without any illustration in my physics book, and there is nothing called conservative force in mathematics to explain it in a math book

Ummm I'm looking for the physical meaning and significant of this

ummm this didn't help

Yes

Why the curl of a conservative force field is zero everywhere?

Does white light contain only the wavelengths of visible spectrum (i.e only from 400nm to 800nm)?
