Discussion
Consider the following sentences -
a. Uniform motion of objects can be shown through graphs.
b. Uniform motion of objects cannot be shown through graphs.
c. Non-Uniform motion of objects cannot be shown through graphs.
d. Non-Uniform motion of objects can be shown through graphs.
e. Velocity of an object is the displacement covered per unit time.
Choose the most appropriate answer from the options given below:
Answer: D
The correct statements are a, d and e.
Both uniform and non-uniform motion can be shown on graphs. Uniform motion gives a straight-line distance-time graph, and non-uniform motion gives a curved one. So a and d are true, and b and c, which deny this, are false.
Statement e is the definition of velocity: the displacement of an object per unit time, in a given direction.
Every option other than D includes b or c, so they are wrong.
