Question

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

  1. v = u + at
  2. s = ut + ½ at2
  3. v2 = u2 + 2as
  4. None of the above

hintHint:

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?
