Question

Which motion(s) among the following are restricted to a plane?

• A. One-dimensional motion
• B. Two-dimensional motion
• C. Three-dimensional motion

Answer 1

Answer: (A), (B)

Two-dimensional motion

One-dimensional motion is shown by a line.

A line lies in a plane.

Two-dimensional motion is shown by a plane.
Three-dimensional motions are not restricted to the planes, they require a $3D$ space to represent them.


One-dimensional motion and two-dimensional motion are restricted to a plane.

Therefore, options (a.) and (b.) are the correct answers.
