comment Meaning the symbol, $W$ and $dW$
$dW$ represents the infinitesimally small change in $W$, i.e, $W_2-W_1=dW$ where $W_1$ and $W_2$ are work done between infinitesimally small period.

comment Earth's magnetic field and the equator
Magnetic force experienced by the charged particle is always perpendicular to the component of Magnetic field and velocity.

comment Why don't fluorescent lights produce shadows?
At first I didn't even needed to read the answer, it was the animation that explained everything. Great answer!

I recommend you to modify your question again since it's quite deviating.

comment Rolling without slipping and friction
Exactly! Ball will be needing a torque to do rotational motion. Any guesses from where will it come from? Its obviously the "frictional force" that will offer the torque to the ball which will further lead to the completion of circular motion.

comment Rolling without slipping and friction
Question need some serious corrections because I am not able to conclude that what you really want to ask? But here is something for you. Friction being "a necessary evil" is important to exist for the relative motion between two surfaces. If there is no friction the ball will keep on slipping and there will be no relative motion.
