Question

If an object moves along a straight path it is said to be _______ or _______ motion. Fill in the blank.

• A. Linear
• B. one dimensional
• C. two dimensional
• D. both A and B

Answer 1

The correct option is D both A and B

Linear motion (also called rectilinear motion) is one dimensional motion along straight line. It is called one-dimensional motion, because we can represent it using only one dimension/variable in a coordinate system. For example, we don't need both x and y variables to describe a linear motion. We can either use x or y.
