Physics 101 quizlet1/30/2024 ![]() ![]() Provides for the inter-conversion of units among all branches of science. system international (SI) units Also known as the International System of Units: Most modern Metric System, Based on the Metric System, Extension of the MKS System, Uses seven basic units, Preferred system of measurement in science and medicine. MKS system Based on the meter (m), kilogram (k), and second (s) CGS system Based on the centimeter (cm),gram (g), and second (s) metric measurement system Also known as the Centimeter, Gram, Second (CGS) or Meter, Kilogram, Second system (MKS). In the process of being replaced by the International System of Units. Used in the United States and parts of the British Commonwealth. Based on the foot (ft), pound (lb), and second (s) Metric System english measurement system Also known as the British Engineering System (Source: Webster's 9th New Collegiate Dictionary) There are two systems: Represent fractions that have denominators that are powers of ten measurement A figure, extent, or amount obtained by measuring DIMENSION. decimal point A dot that separates the ones digit and the digit immediately to its right decimal numbers Numbers to the right of the decimal point are called decimal numbers. When pushing a heavy block, the block will push back with the same force applied powers of ten A system used to express large and small numbers too cumbersome to write in ordinary notation. There are three laws newton's first law (Law of Inertia) - A body will remain at rest or if in motion will continue moving at a constant velocity in straight line unless acted upon by an external force newton's second law - The force acting on a body is proportional to it's mass times it's acceleration the direction of the force is the same as that of the body's accelerationį = ma newton's third law (Action/Reaction) - For every action there is an equal and opposite reaction. Scientific method Comprises the systematic collection of facts of the study of their interrelationship, and the drawing of valid conclusions from the resulting data laws of motion Developed by Sir Isaac Newton in 1686
