One-dimensional linear position is measured along a line, from a point designated x = 0.One-dimensional angular position:
A)is measured along a line, from a point designated θ = 0.
B)is measured along the axis of rotation.
C)is the angle that an internal reference line makes with a fixed external reference line.
D)is measured relative to the positive y axis.
E)is meaningless, as rotations take place in two dimensions.

Question

Quizplus · Accepted Answer

One-dimensional angular position is defined by the angle an internal reference line (such as a line drawn on a rotating object) makes with a fixed external reference line (such as a line on the surface the object is on or a line representing a fixed direction in space). This concept is crucial in understanding rotations and angular motion in physics.
