Measurement

Phsics is based on measurement of physical quantities. Certain physical quantities have been chosen as base quantities, each has been defined in terms of standard and given a unit to measure. Other physical quantities are defined in terms of base quantities and their standard and units. The Internal System of Units (SI) will be used throughout this course. During this week, the learning goal will focus on measuring things, changing various units, defining length, mass and time and understanding significant figures and decimal places. in the last lecture we will understanding the basic concept of density and quantities related to it. Our main goal will be problem solving.
