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.
Centripetal force acts at right angles to an object's circular motion so the force changes the direction of the object's velocity. If the force vanishes, the object stops moving in a circular path and instead moves along the straight tangent path where the force left it.
