masses

A proton is actually a hydrogen atom, which has lost its electron. Since the mass of an electron is small, the mass of a proton is equal to the mass of a hydrogen atom. As the mass of hydrogen atom is 1 a.m.u., the relative mass of a proton is 1 a...

Mass - The SI unit is kilogram. 1 kg is defined as the mass of a platinum-iridium cylinder kept at the International Bureau of W and M at Sevres, France, established in 1887. The atomic structure of mass is yet to be develop..

Mass - Mass is the quantity of matter in the body. Mass is measured by finding out the force needed to change the way the object moves. The greater the force needed, greater the mass of the object. If you push a book, it moves faster than if you push a car wi..

Mass is the quantity of matter contained in a body. If you push a book, it moves faster than if you push a car with the same force. This is because the car has more mass than the book. If you had two identical boxes, one containing iron and the other containing cotton we could i..

The mass of a body can be determined by measuring the acceleration 'a' produced in it by a known force 'F..

Mass can be determined by comparing the weight of it with the weight of a known mass, a standard mass. For this we can use a lever balance on common balanc..

Mass and Weight - Mass and weight are commonly mistaken as the same, but they are two different quantities. Now let us try to find out the differences between th..

It is the mass of a body measured when it is not in motion under the effect of gravity. It is measured using a physical balance. Though the inertial mass and gravitational mass appear to be different, in actual practice they are treated as same, since the difference b..

An indirect method to determine the absolute mass of an atom has been devised. The mass of a particular atom is taken as a standard unit and the masses of other atoms are related to this standard. Hydrogen being the lightest element and being the smallest atom was chos..
