Does kinetic energy of a body in a free fall depend on mass

The kinetic energy of the body under free fall increases till it hits the surface. When the body is stationary at a height, all it has is potential energy. Under free fall, the speed of the body increases (depends upon gravitational acceleration, on earth it is approx. 9.8 m/s^2) as it moves closer to the surface and so, does the kinetic energy of the body.
**In classical mechanics, Kinetic energy is directly proportional to the square of the speed of the body**

Yes kinetic energy is dependent on the mass of the body .
Kinetic energy=1/2 *mass *velocity^2.
