Question

The velocity – time graph of a particle starting from rest with uniform acceleration is a straight line

• A. not passing through origin
• B. parallel to time axis
• C. parallel to velocity axis
• D. having none of the above characteristics.

Answer 1

The correct option is D having none of the above characteristics.

(a) Since initial velocity is zero, therefore, the velocity- time graph must pass through the origin.
(b) Since velocity is increasing at a uniform rate therefore, the velocity- time graph cannot be parallel to time – axis.
(c) If the velocity- time graph is parallel to velocity axis, then it would mean different velocities at any given time. This is physically impossible.
