Question

In which of the following cases can the equations of motion not be applied?

  1. Free fall
  2. A car moving at a constant speed of 3 m/s
  3. A randomly moving car
  4. A car moving at a constant acceleration of 3 m/s2

hintHint:

The equation of motion is only applicable when the body moves with uniform acceleration.

The correct answer is: A randomly moving car


    The equation of motion is not applicable for A randomly moving car.

    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.
