Question
The v-t graph of a body is a straight line with a positive slope. Which of the following is true about the body’s motion?
a. It is in a uniform motion
b.Its velocity is constant
c. Its velocity increases by equal amounts in equal intervals of time.
d. Its velocity decreases by equal amounts in equal intervals of time.
- Only a, b, and d are incorrect
- Only a and d are correct
- Only b and c are correct
- Only d is correct
Hint:
Only a, b and d are incorrect
The correct answer is: Only a, b, and d are incorrect
The v-t graph of a body is a straight line with a positive slope which shows that its acceleration increases by equal amounts at equal intervals of time. Hence, it is in non-uniform motion with variable velocity i.e., its velocity increases by equal amounts at equal time intervals.
