Fundamental and Derived Quantities

This lesson covers the definitions of fundamental and derived quantities in physics. It explains how fundamental quantities serve as the base for deriving other quantities and the importance of measurement in physical science.

• 22:06 “As established mathematically, the weight of an object is the poorer of mass and the acceleration due to gravity. That is, mass m, mass m times g, which is the acceleration due to gravity. And that is the formula on the...”
• 22:53 “So multiplying 50, which is the mass of the man, times the acceleration due to gravity, which is 9.8, we have 490. And I showed you that weight or the force of an object is usually measured in new things. So the unit is...”
• 20:28 “So I need to clarify this more and more at this point in time. When we talk about mass, we are talking about the quantity of matter contained in a body. The quantity of matter contained in a body. And the mass of an obje...”
