Question

Which of the following is not possible for a body in uniform motion?
(The shown graph is Displacement vs Time)
A.
B.
C. Both A and B
D. None of these

Answer 1

Hint: The motion in which the object travels in a straight line with uniform speed, is known as uniform motion. This means the velocity of the body remains constant as it covers equal distances in equal intervals of time.

Complete step by step solution:
As we are going to find which one of the following is not possible for uniform motion. In a uniform motion, a body covers equal distances in an equal interval of time. If we consider the graph, by seeing this graph we can say that the body is at rest, that is, there is no motion of the body.

Similarly, if we consider the second graph, here the time taken to move a body is zero or constant, which is not physically possible, that is the body can't have displacement in no time. Therefore, both graphs A and B do not show the uniform motion.

Hence, option C is the correct answer.

Note:There are two types of motion one is uniform motion as we discussed above and the other one is non-uniform motion. A type of motion in which the object travels with a varied speed is called non-uniform motion. This means the object does not cover equal distances in equal time intervals. A car going along a straight level road at a constant speed. A train that is moving along straight tracks at a steady speed etc is an example of uniform motion. Usually, most of the motion around us is non-uniform, that is, an airplane moving through the clouds and then landing, a man running in a 100m race, etc.
