Question

An object starts from rest. It means that _____.

  1. Its initial velocity is zero
  2. Its final velocity is zero
  3. Its acceleration is zero
  4. Its displacement is zero

hintHint:

It's initial velocity is zero

The correct answer is: Its initial velocity is zero


    When an object starts from rest it means that it's initial velocity is zero.

    Rest implies that the body was stationary with respect to the ground. Any body which doesn't move has zero velocity, since it doesn't covers any distance. Thus, any body starting from rest has initial velocity= zero.

    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?
