For sorrow, like a heavy–hanging bell, once set on ringing, with his own weight goes. In the United States, the units of mass and weight are the same. Some people experience only a few symptoms while others may experience many. 1. The poundal is the force needed to accelerate a 1-lb mass at 1 ft/s2. Weight is the product of mass multiplied by acceleration acting on that mass. The total amount of organic material produced by living organisms in a particular area within a set period of time, called the primary or secondary productivity (the former for plants, the latter for animals), is usually measured in units of energy , such as gram … In other words, mass is a scalar quantity while weight is a vector quantity. Synonym: Ponderousness, gravity, heaviness, pressure, burden, load, importance, power, influence, efficacy, consequence, moment, impressiveness.
