clockwise
adv 1: in the direction that the hands of a clock move; "please
move clockwise in a circle" [ant: {anticlockwise},
{counterclockwise}]
adj 1: in the same direction as the rotating hands of a clock
[ant: {anticlockwise}, {contraclockwise},
{counterclockwise}]

clockwise \clockwise\ adj.
1. -- of rotatory motion. {dextral}
[WordNet 1.5]


clockwise \clock"wise`\, a. & adv.
in the same direction as the hands of a clock rotate, as
viewed from in front of the clock face; -- said of that
direction of a rotation about an axis, or about a point in a
plane, which is ordinarily reckoned negative. Also said of
the direction of a spiral, in which case the term
{right-handed} is more common. Opposite of
{counterclockwise}, and {left-handed}.

Syn: right-handed, dextrorotary, dextrorotatory.

  • 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 is useful because the direction is "counter-clockwise or clockwise depending on what side of the plane you are looking at"
  • Why is a clockwise moment negative by convention?
    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 My thoughts: It doesn't matter which -wise you assign $+$ or $-$ as long as you are consistent
  • Why is induced electric current moving clockwise counterclockwise?
    Hence for north pole approaching or a south pole moving away, the current runs counter-clockwise When the north pole is moving further away or the south pole is moving closer, the opposite is true: the change in flux is negative, thus the line integral of the electric field is positive By the same logic as above, the current then runs clockwise
  • Difference in winding a coil clockwise vs counter clockwise
    When the current travels away from you the magnetic field lines go in the counterclockwise direction Lines of force go from north to south, supposedly So if you wound your wire clockwise, in the direction it's going, the north pole of induction would be where the wire started How would this affect current though, is what I'm asking
  • Why does earth spin counter-clockwise? - Physics Stack Exchange
    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 sundials to measure the time, and so the shadow's motion defined what we call clockwise, as the direction was transferred to later mechanical clocks
  • 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 seen from above the North pole, the Earth rotates in a counter-clockwise direction, whereas when seen from above the South pole, it rotates
  • Direction of magnetic field in a solenoid
    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 pole of the power source (e g: battery), then the end of the solenoid that you are going to connect to it
  • Do electrons in an atom always have the same direction?
    Perhaps speaking of direction of an electron isn't quite correct But does QM indicates a kind of way whether all electrons are going e g 'clockwise' or not? 'Direction' isn't quite correct, and nor is 'clockwise' For an analogy, imagine a glass clock, without any numbers on its face The hands are rotating in a clockwise direction
  • When are torques positive or negative? - Physics Stack Exchange
    In the above problem, however, it seems the clockwise rotation of the pully is defined to be positive and counterclockwise rotation negative In this case, the sign is simply a result of whatever direction we decide to define as positive and indicates whether the angular rotation is clockwise or counterclockwise
  • Direction of Current, according to Lenzs law, from induced EMF
    A clockwise current is induced in the loop, increasing the strength of the magnetic field into the page, and thus offsetting the change in flux The same answer is arrived at by considering the Lorentz force: charge carriers in the moving wire are subject to a force due to the fact that they're moving through a magnetic field
