Consider two boxes of masses, m and 2m, both initially at rest. You push each box separately with a force, F, over a distance ,d, across a frictionless surface. How does the final kinetic energy of the lighter box compare to the final kinetic energy of the larger box.

Friction removes energy from objects in motion. which statement best describes how this works? a) friction transforms ke into thermal energy b) friction transfers thermal energy to ke c) friction transforms te into pe d) friction transforms pe into ke e) friction transfers ke into pe
