Basics, what happens if you drop two different bodies from the same height and at the same time? - Fundamental, in what way could the influence of the acceleration of gravity be controlled or diminished? - Fundamental, what factors could influence the speed of the object during free fall?

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.
