When you are on a swing, and at the lowest point of your motion, is your apparent weight greater than, less than, or equal to your true weight? explain

In a circular motion there must be a centripetal force directed towards the center. At the bottom of the swing trajectory we can pretend you are in uniform circular motion, so the net force points up toward the center of the circle. Therefore, the swing must exert a larger upward force on you than the earth does in the downward direction. So your apparent weight is greater than your true weight.

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.
