Mass and Weight
- Mass is a measure of the atoms contained in an object, and the number of atoms in the object remains constant. So, mass is an intrinsic, unchanging property of matter.
- The force with which a body is attracted towards earth is called weight.
- W=mg. Where W is weight and m is mass.
- Mass is measured with the help of a physical balance, while a spring balance measures the weight of an object.
