PPT-Introduction to Significant Figures

amp Scientific Notation Significant Figures Scientist use significant figures to determine how precise a measurement is Significant digits in a measurement include all of the known digits plus one estimated digit. Physical quantities. Any quantity that can be quantified by measurement is a physical quantity . Most of the quantities we deal with as scientists are physical quantities and they will be the ones we will discuss throughout this topic of motion.. Physical Science. What is a significant figure?. There are 2 kinds of numbers:. Exact: the amount of money in your account. Known with certainty.. What is a significant figure?. Approximate: weight, height—anything MEASURED.

The engine careened across almost 100 feet (30 meters) of the station concourse, crashed through a two-foot thick wall, shot across a terrace and sailed out of the station, plummeting onto the Place de Rennes 30 feet (10 meters) below where it stood on its nose. While all of the passengers on board the train survived, one woman on the street below was killed . …Matter is anything that occupies space.. The Six Levels . of Thought. Knowledge. Comprehension.
