Question

Which of the following is/are example(s) of linear motion?

• A. Motion of a snake.
• B. Motion of soldiers in a parade.
• C. Motion of train on a straight bridge.
• D. Motion of a flying butterfly

Answer 1

Answer: (B), (C)

The correct options are
B Motion of soldiers in a parade.
C Motion of train on a straight bridge.

Motion in a straight line is called linear motion.
Motion of soldiers in a parade is in a straight line. Similarly motion of a train on a straight bridge is an example of linear motion.
Motion of a snake or a flying butterfly is very random as they don't move in a definite direction. Hence cannot be termed as linear motion.
