Now you're beginning to rotate backward, and the question arises, How do you know how much to rotate?
(If one wheel is rotating backward, which is possible in very tight turns, its speed should be counted as negative.)
Both hands are kept flat on the floor while the body rotates backward through a handstand.
The van's wheels began to rotate backward, but the van did not move.
Among the many effects this causes is one of interest; the blades rotate forward and backward around the hub as drag increases and decreases.
Consequently, since rotations can be undone by rotating backward, quantum computations are reversible.
The palms of the hands are cupped and made to rotate backward, again as if scooping a solid substance.
Notice how your hands rotate backward.
The major stayed on the ground, watching him clamber over the tank's treads then to the top of the Tiger's turret, rotated backward for transport.
