Question

# Which of the following is called the position-time relation?

- v = u + at
- s = ut + ½ at
^{2} - v
^{2} = u^{2} + 2as - None of the above

^{2}^{2}= u^{2}+ 2asHint:

### s = ut + ½ at²

## The correct answer is: s = ut + ½ at^{2}

### 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?
