Question

Which BEST compares the motions of dots C and D?

Answer 1

Option C is correct as c is speeding up but d moving with same or constant velocity

Answer 2

As per the graph there is a motion map which denotes the motion of two dots C and D respectively.

As per the graph the motion of dot C is non uniform .It is so because it is covering unequal distance in equal interval of time.Its speed is increasing at every instant .Hence it is speeding up.

The motion of dot D is uniform .It covers equal distance in equal interval of time.Hence the dot D is moving at a constant velocity.

Hence out of four options given in the question,the third option i.e C is the correct answer .
