In coordinate planes, angles are usually measured counterclockwise, starting from 0°, which is on the right-hand end of the coordinate plane. There are special cases however, where clockwise rotation loosens, and counterclockwise rotation tightens. This is because more people are right-handed than left-handed, and it is generally easier for a right-handed person to tighten a screw clockwise than counterclockwise.
They are usually designed to be tightened when turned in a clockwise direction with respect to the person looking at the object, and loosened when turned counterclockwise. For example, many objects such as jar lids, screws, bolts, bottle caps, nuts, and more, need to be turned a specific direction to be tightened or loosened. Other usagesĪlthough the term clockwise originated with the use of clocks, it is also used in other areas. The rotation of the Earth is clockwise if viewed from above the South Pole, but counterclockwise if viewed from above the North Pole, where "above" means farther away from the center of the Earth. If there were someone else on the other side of the wall who could see the same rotation that we were looking at, from their perspective, a clockwise rotation for us would be counterclockwise for them.Īnother example is the rotation of the Earth. Another possible direction is a person standing on the other side of the wall. For example, looking straight at a clock on a wall is one possible direction.
COUNTERCLOCKWISE ROTATION RULE HOW TO
Refer to the time page to learn more about various aspects of time or about how to read an analog clock.īoth the terms clockwise and counterclockwise are defined based on looking at the clock from a specified direction. The opposite direction of motion is described with the term counterclockwise. In the image below, the arrows indicate a clockwise direction:
With reference to the numbers on a clock, they are passed in order from least to greatest, starting from 12, which is the 0 position of a clock.
Looking at a clock from the front or above, the hand of a clock moves right and around in a circular motion. The term clockwise describes the direction in which the hands of a clock move. Home / primary math / time / clockwise Clockwise
