Question

A car moving straight on a straight road is an example of

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

Answer 1

The correct option is A One-dimensional motion

A car moving straight on a straight road can be shown as:

$\underset{–}{TopView:}$


$\underset{–}{SideView:}$


Since the car moves in $1$ direction only and is also moving straight, it is an example of one-dimensional motion.

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