The correct answer is Acceleration is constant all throughout the free fall.

Key Points

  • An object that is moving only because of the action of gravity is said to be free-falling and its motion is described by Newton's second law of motion.
  • The acceleration of the freely falling object is constant and equal to the acceleration due to gravity.
  • Acceleration due to gravity is denoted by the symbol - g.
  • g = 9.8 m/s2 at sea level on the Earth.
  • Its SI unit is m/s2.
  • The dimensional formula is given by [M0 L1 T-2].
  • Acceleration due to gravity is a vector quantity, which means it has both a magnitude and a direction.
  • The value of acceleration due to gravityg’ is affected by:-
    • Altitude above the earth’s surface.
    • Depth below the earth’s surface.
    • The shape of the earth.
    • Rotational motion of the earth.
  • A free-falling object has only one external force which is the gravitational force. So it experiences constant acceleration.

Additional Information

  • Zero acceleration does not imply zero velocity, as a body moving with a constant velocity can have zero acceleration and the body is in motion.
  • Zero acceleration has a relation with the velocity of the object as it implies the body is at constant velocity.
  • The zero-velocity of a body at any instant does not necessarily imply zero acceleration at that instant.
  • The kinematic equation of motions is true only for motion in which the magnitude and the direction of acceleration are constants during the course of motion.
