The CORRECT > formula is: KE = a/g (m) + v / 32.174 (m). At the end of second one, > KE = 2. Your formula may be YOUR definition of energy, but it is not anyone else's definition. Kinetic energy is not "splat power". Let us go back to MY questions. 1) If I lift an object 64 feet, is the energy it took me to lift it the first foot equal to the energy it took me to lift it the second foot, third foot, fourth foot... sixty-third foot, sixty-fourth foot? Yes/No 2) If I drop an object 64 feet, is the kinetic energy acquired by the object equal to the energy that it took to lift it 64 feet? Yes/No 3) If I drop an object, does it fall about 16 feet the first second, and after two seconds, is the total distance fallen approximately 64 feet? Yes/No 4) Is 16 equal to one-fourth of 64? Yes/No 5) Is the amount of potential energy converted to kinetic energy after one second equal to one-fourth the amount of potential energy converted to kinetic energy after two seconds? Yes/No I need to know at what point you start saying "No". Jerry
