What does "clockwise" mean, exactly? - Physics Stack Exchange
The answer too makes explicit reference to the right hand rule to define clockwise. One answer to Applying the right-hand rule for magnetic forces explicitly uses the right hand rule, and explains that it …
Why does earth spin counter-clockwise? - Physics Stack Exchange
Jul 24, 2015 · But there is a clear reason why it is clockwise: Earth's spin cuases an apparent motion of the sun during the day, which causes shadows to turn around objects. This was used to construct …
How does Earth rotate on its axis, clockwise or anti-clockwise?
This is essentially a meaningless question unless you specify a system with respect to which you define both clockwise and anti-clockwise. If you don't do this, then there really is no way to answer: when …
Why is a clockwise moment negative by convention?
Aug 12, 2016 · My physics book states that by convention a clockwise moment is said to be negative and an anti-clockwise moment is said to be positive. I'm curious about the origin of this convention.
Why and how does the 'clock rule' of electromagnetism (i.e. current ...
Can anybody explain why the 'clock rule' has been designed the way it is? I mean, why is it that the polarity is North pole, if current flows in the anticlockwise sense as viewed from above and vice-
Direction of magnetic field in a solenoid - Physics Stack Exchange
The north and south pole of a solenoid depends on two factors. One, the direction of the current flow and two, the direction of the winding (clockwise or counter-clockwise). Start by determine the positive …
Why do wheels spin? - Physics Stack Exchange
Apr 1, 2016 · In my physics textbook it says cars move because the wheels exert a backward force on the ground and the ground exerts an equal and opposite forward force on the car. If the wheel spins …
Difference in winding a coil clockwise vs counter clockwise
Nov 1, 2020 · I was watching a YouTube video on the difference of winding a coil clockwise vs winding a coil counter clockwise. It said the poles would be opposite using the same battery configuration.
How to determine the direction of induced current flow?
Aug 10, 2015 · where B B → is the magnetic field and E E → is the induced electric field.That may appear, to an elementary student, to be a bunch of gobbledygook, but it means "the electric field …
homework and exercises - Physics Stack Exchange
Jul 11, 2016 · Is it always true, for any cycle followed by a gas, that, if the cycle is "travelled" clockwise in the P−V P V plane then the work exchanged by the gas is positive, and viceversa for the clockwise …
