When we move something in a clockwise direction, it is moving in the same direction as the hands on the clock.Įxample of clockwise: Most screws, lock,s and taps are closed by turning in the clockwise direction. These two terms are used for indicating the direction. The rotation in a two-dimensional plane about a fixed point can be of two types- clockwise and counterclockwise. ![]() This is what causes lift, as well as the force that will cause a spinning propeller to push or pull an aircraft. This is because the spinning of a blade creates lift, and in turn causes airflow which pushes against surfaces on one side with high pressure and pulls on the surfaces of an adjacent object with low pressure. The opposite happens when you spin the blade counterclockwise: there is a low-pressure zone around your hand. You will notice that when spun clockwise, the blade will create a high-pressure zone around your hand. Spin it by using your other hand to spin the blade clockwise or counterclockwise. Take a fan blade and place it flat side down on top of the opening to your hand while you are holding your hand up to the opening. counterclockwise when placed in front of an opening, and the difference in airflow through two fans rotating in opposite directions. To do this, there are two things that will be demonstrated: the effect of a fan blade rotating clockwise vs. This demo is to help you understand the effects of clockwise and counterclockwise rotating propellers on pressure. This demonstration will help you understand how this directly affects pressure on each side of a propeller or fan blade as it spins. The terms clockwise and counterclockwise are used to describe the direction in which a rotating object turns.
