Question

Which of the following is/are true for a freefall?
a. It is a uniform motion in which an object falls towards the center of the earth.
b. It is an accelerated, non-uniform motion in which an object falls towards the center of the earth.
c. It is a uniformly accelerated motion.
d. The acceleration due to gravity is 9.8 m/s2.

  1. Only b, c, and d are correct
  2. Only a is correct
  3. All are correct
  4. Only b and d are correct

hintHint:

Body falling freely doesnt move with unifrom velocity.

The correct answer is: Only b, c, and d are correct


    Freefall of a body is a Uniform accelerated motion in which the object accelerates towards the earth. The acceleration due to the gravity is 9.8 m/s^2.
