Ashok Sharma Solutions for Chapter: Motion in a Straight Line, Exercise 1: SELF EVALUATION TEST

What is indicated by the slope of position-time graph ?

Can displacement be greater than distance travelled by a body?

Is it true that in one-dimensional motion a particle with zero speed may have non-zero velocity? Explain.

Can a body be said to be at rest as well as in motion at the same time? Give one example.

Define motion in one, two and three dimensions giving one example of each.

State and explain the concept of displacement. Mention at least it's five characteristics.

For a particle moving with constant velocity, show that  $x=x_0+vt$ or $s=vt$.

where,

$x_0$= initial position of the object

$x$= final position of the object

$s$= displacement of the object

Define relative velocity. Show that the relative velocity of an object $"2"$ relative to another object $"1"$ moving in one dimension is $v_2-v_1$.
