Consider two identical objects released from rest high above the surface of Earth. (Neglect air resistance for this question.)
In Case 1, the object is released from a height above the surface of Earth equal to 1 Earth radius, and its kinetic energy just before it hits Earth is K1 . In Case 2, the object is released from a height above the surface of Earth equal to 2 Earth radii, and its kinetic energy just before it hits Earth is K2 .
1. Compare the kinetic energy of the two objects just before they hit the surface of the earth.
