The law of conservation of mass states that the total mass of a system remains constant during a chemical reaction or physical change. In other words, the mass of the products in a chemical reaction must equal the mass of the reactants. This law is a fundamental principle in c...

the discrepancy between the two values becomes larger as the object travels faster. The relativistic form of an object's energy incorporates correction factors such as the rest-mass energy and the Lorentz factor to make th...

The force of gravity acting on an object is also that object's weight. When you step on a scale, the scale reads how much gravity is acting on your body. The formula to determine weight is [source: Kurtus]: weight = m x g where m is an object's mass, and g is the acceleration...
