1.1 Physical quantities and measurement techniques Describe the use of rulers and measuring cylinders to find a length or a volume Describe how to measure a variety of time intervals using clocks and digital timer Determine an average value for a small distance and for a short interval of time ...
Units are standards for expressing and comparing the measurement of physical quantities. All units can be expressed as combinations of four fundamental units. The four fundamental units we will use in this text are the meter (for length), the kilogram (for mass), the second (for time), and...
