2. Mass Weight 3/25/2017 8-L The SI unit of Mass is Kilogram
The SI unit of Weight is Newton
Mass is the amount of matter present in a body and is an intrinsic property of the body. Mass of an object remains the same always at any place.
Weight is a measure of how strongly gravity pulls on that matter.
Mass is measured using a pan balance, a triple-beam balance, lever balance or electronic balance.
Weight is measured using a spring balance
