Question
Which of the following is called the position-time relation?
- v = u + at
- s = ut + ½ at2
- v2 = u2 + 2as
- None of the above
Hint:
s = ut + ½ at²
The correct answer is: s = ut + ½ at2
s = ut + ½ at² is called the position-time relation.
s = distance travelled by the body
u = initial velocity
t = time taken by the body
a = acceleration of the body
s = ut + ½ at² is position-time relation as it has both the components of position and time.

Mira plotted a s-t graph of her car journey by collecting data during a drive. She started from rest and slowly increased her velocity until it reached a particular value. Then she maintained a uniform motion. Lastly, she slowed down gradually to bring the car to a stop. Which of the following graphs would resemble the graph plotted by Mira?
