Clockwise torque is positive or negative
WebNote that each force that acts in the counterclockwise direction has a positive torque, whereas each force that acts in the clockwise direction has a negative torque. The torque is greater when the distance, force, or perpendicular components are greater. Determining clockwise vs counter clockwise rotations WebMar 28, 2024 · If the object is rotating counterclockwise, the torque is positive. If the object is rotating clockwise, the torque is negative. For example, if the object is moving …

Answer 2: negative. Angular velocity [is/is not] constant when a skater pulls in her arms, when a child starts up a merry-go-round from rest, or when a computer's hard disk slows to a halt when switched off. In all these cases, there is an angular acceleration, in which ω [remains constant/changes].
