Review the work-energy theorem and apply it to a simple problem. if you push a particle of mass m in the direction in which it is already moving, you expect the particle's speed to increase. if you push with a constant force f, then the particle will accelerate with acceleration a=f/m (from newton's 2nd law).

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.
