Question

Which of the following is/are correct regarding uniform and non-uniform motion?

• A. For the body to be in the uniform motion, it must be moving in the straight line path
• B. The slope of displacement-time graph for uniform motion is constant and gives constant velocity
• C. A car coming to a halt is an example of non-uniform motion
• D. All of the above

Answer 1

Answer: (D)

All of the above

Two sentences are correct regarding uniform motion:

$1.$ The body must be moving in a straight line path.

$2.$ The slope of displacement time graph for uniform motion is constant and gives constant velocity.

In other words, the velocity should be constant, i.e. its direction and magnitude should be constant.

A car coming to half is an example of non-uniform motion as its speed changes with time, the sentence is correct regarding non-uniform motion
