Question

The motion of a billiard ball on a billiard table is a/an

• A. one-dimensional motion
• B. two-dimensional motion
• C. three-dimensional motion
• D. zero-dimensional motion

Answer 1

The correct option is B two-dimensional motion

The billiard ball can move right, left, forward or backward (after hitting from the table) when hit by the billiard stick.

The motion of a billiard ball is restricted to one plane only and is also a planar motion or $2D$ motion.

The motion of a billiard ball on a billiard table is a two-dimensional motion.

Therefore, option (b.) is the correct answer.
