A 2D (two-dimensional) barcode is a graphical image that stores information both horizontally -- as one-dimensional <term>bar code</term>s do -- and vertically. As a result of that construction, 2D...
Centripetal force is the inward-seeking pull of an object. Centrifugal force is the opposite; it appears to pull objects away from the center or axis of rotation.
1 It works in conjunction with the Coriolis force to give correct motion. ( 2 physics): In circular motion, the 'reactive' centrifugal force is a real force applied by the accelerating body that is equal and opposite to the centripetal force that is acting on the accelerating body.
