Apackage rests on the floor of an elevator that is rising with constant speed. the elevator exerts an upward normal force on the package, and hence does positive work on it. why doesn't the kinetic energy of the package increase?

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
