Why is a clockwise moment negative by convention?

WebIf the angle is positive, the terminal side rotates counter clockwise, and if the angle is negative, the terminal side rotates clockwise. For example, if the terminal side was on the the positive y-axis (above the origin), then the angle made would be 90 degrees, because the terminal side rotated 90 degrees counter clockwise. Hope this helps! WebApr 30, 2024 · Clockwise rotations are denoted by negative numbers. Counterclockwise rotations are denoted by positive numbers.
