A three-wheeler starts from rest, accelerates uniformly with 1 m s-2Â on a straightÂ road for 10 s, and then moves with uniform velocity. Plot the distance covered byÂ the vehicle during the nth second (n = 1,2,3â€¦.) versus n. What do you expect thisÂ plot to be during accelerated motion : a straight line or a parabola ?

Now, putting different values of n in equation (3), we have

 n 1 2 3 4 5 6 7 8 9 10 Sn 0.5 1.5 2.5 3.5 4.5 5.5 6.5 7.5 8.5 9.5
Â
The graph between Sn and n will be a straight line as shown in the figure below.Â

What is rest?

When an object does not change its position with time, with respect to it's surroundings. In such a case the object is said to be at rest.

Is absolute rest or absolute motion possible?

Absolute rest and absolute motion is not possible because there is no point in the universe which is at rest and can be taken as point of reference. The planet Earth is in continuous motion.

What is the most essential thing to study the motion of a body?

The most essential thing to study the motion is reference frame. Rest and motion are relative terms. It means that an object in one situation can be in rest but in another situation, the same object will be in motion.
