Physics is based on experimental observations and quantitative measurements. To identify relationships that characterize nature, we must know how to measure physical quantities. Physical quantities are generally dependent to one another. Mechanics includes three fundamental quantities which are length, mass and time. You will be the learning the relationship between these quantities, how to measure them, errors and graphs.
