Question

A vehicle’s displacement increases by 4 m every second. What does it mean?

  1. Its velocity is 4 m/s
  2. Its displacement is 4 m
  3. Its acceleration is 4 m/s2
  4. Its displacement is 0

hintHint:

Its velocity is 4 m/s

The correct answer is: Its velocity is 4 m/s


    It means its velocity is 4ms-1
    Justification:
    Velocity = change in position / time taken.

    A vehicle’s velocity increases by 5 m/s every second. What does it mean?

    Acceleration can be defined as the rate of change of velocity of an object with respect to time and in this case, the vehicle is also accelerating with a unform change in velocity.

    An object starts from rest. It means that _____.

    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?
