Mass is constant and does not depend on gravity, Where As <span>Weight is the force something exerts from its acceleration due to gravity.
Example: </span>A 100 g sample is 100 g on the earth, on the moon, wherever. <span>Since the force of gravity varies, this amount can vary greatly depending on where the thing was weighed. Even on earth the difference in the force of gravity between different elevations is sufficient for an object's weight to be different.</span>
The 650 skeletal muscles in the human body contract when they receive signals from motor neurons, which are triggered from a part of the cell called the sarcoplasmic reticulum. Motor neurons tell your muscles to contract and the better you become at having those signals tell your muscles to contract, the stronger you can get.
