Abstract:
Weight of a macro body is its acceleration due to gravity, in gravitational units, towards another larger macro body. During variations in temperature, a macro body changes quantity of matter (mass), it contains. Since mass is a factor in equations, to determine gravitational attraction and acceleration, macro body’s acceleration due to gravity does not change by variation in its mass. Concept, presented in ‘Matter (Re-examined)’, consider mass as mathematical relation and matter-content as quantity of matter, a macro body contains. It advocates a mechanism, which causes additional changes in magnitude of gravitational attraction over and above changes caused by variation in macro body’s mass. Thus, it is logical to find that a macro body weighs less, when hot compared to its weight in cooler state.
