1. Mass
Galileo showed convincingly that heavy objects fell no faster that light ones. ... If an iron ball was pulled down with a much greater force than a wooden one of the same size, why didn't it fall any faster? ... 1) It is harder to lift. ... It is the fact that the loaded wagon has a greater mass that gives it a larger inertia , a larger tendency to oppose any change in its state of rest or of constant motion in a straight line. ... One important quantity was the body mass of the astronauts. ...

... The Stellar IMF at Low Masses: A Critical Look at Variations and Environmental Dependencies . ... View Registration . ... The shape of the stellar initial mass function (IMF) is one of the main uncertainties in our understanding of star formation, i.e., the conversion of gas into stars over cosmic time. ... The main purpose of this workshop is to have a critical look at current and new evidence for variations of the IMF at sub-solar stellar masses. ... The registration fee is $200.00. ...

3. Dark Matter in the Universe
So the evidence for Dark Matter is fairly overwhelming. ... Theory: if the Universe is closed then all the luminous matter seen in galaxies contributes only 0.5% of the mass required to eventually halt the expansion . ... This means that galaxies are surrounded by dark matter halos which trapped baryonic gas (e.g. hydrogen) and turned it into stars. ... WIMPS - weakly interacting massive particles created in the extremely early universe . ... Theory 99% of the Universe is Dark Matter . ...

5. Mass
... The difference is that inertia is an inherent property of matter, while weight also depends on gravity. ... They use gravity, balancing its force on the astronaut's body against a calibrated spring or against the force of gravity on some calibrated weights. ... Using scales and the local force of gravity, one can determine gravitational mass; or else, one might dispense with gravity, like the astronauts aboard Skylab, sand measure the "inertial mass," and in principle they may differ. ...
