Group 6 blog on mass



Mass
What is mass?Mass is the amount of matter in a substance.
The SI unit for mass is kilograms (kg)
Other units for mass: tonnes, grams, milligrams
Sometimes,we have to convert grams into kilograms,milligrams into kilograms and so on...

Most people are confused with mass and weight. Well, they aren't the same.
Mass of a substance depends on the number of particles which make up a substance and cannot be changed by the location of a substance.
Weight is the gravitational force acting on a matter and can be changed with the location of a substance.
Some instruments used to measure mass are the beam balance and Electronic balance.
