Question

Which of the following value(s) can the displacement take?

 

  1. > 0
  2. < 0
  3. = 0
  4. All of the above

hintHint:

All of the above

The correct answer is: All of the above


    Displacement can be zero, positive (>0), and even negative (<0).
    Justification: 
    When the initial and final point of an object is the same then the displacement will equal ZERO
    When the object moves in a forwarding direction with reference to the initial point then the displacement will be POSITIVE
    When the object moves in a backward direction with reference to the initial point then the displacement will be NEGATIVE.

    Peter wants to modify the formula for acceleration
    i.e., a = (v – u)/ t
    Where v = final velocity, u = initial velocity, t= time, a = acceleration, to suit the special case of freefall of a ball dropped from the top of a building. He chooses to make the following substitutions in the formula.
    a. v= 0
    b. u= 0
    c. a= 9.8 m/s2
    Identify the correct substitutions.
