Question
Write a short note.
Free Fall

Answer

  1. The motion of any object under the influence of the force of gravity alone is called free fall.
  2. In free fall, the initial velocity of the object is zero and goes on increasing due to the acceleration due to gravity of the earth.
  3. During free fall, the frictional force due to air opposes the motion of the object and a buoyant force also acts on the object.
  4. Thus, true free fall is possible only in a vacuum.
