Legault, Minnesota Literacy Council, 2014 3 Mathematical Reasoning Lesson 11 Activity 2: Metric Measurement Time: 25-30 Minutes 1) Every measurement in the metric system is based on 10. To find an equivalent measurement, you multiply or divide by 10, 100, or 1000. Once you memorize the prefixes, • Density: Mass per unit volume – SI Units: kg/m3 • Specific heat: Energy required to raise the temperature of unit mass of material by one unit – SI Units: J/kg K • Velocity: Distance traveled per unit time – SI Units: m/s • Energy: Capacity to do work – SI Units: J (or N m) • Work: Transference of energy – SI Units: J (or N m) Thus physics is inherently a science of measurement. The fundamentals of physics form the basis for the study and the development of engineering and technology. Measurement consists of the comparison of an unknown quantity with a known fixed quantity. The quantity used as the standard of measurement is called ‘unit’. A standard unit of measurement is a quantifiable language that describes the magnitude of the quantity. It helps to understand the association of the object with the measurement. Although measurement is an important part of everyday life, kids don't automatically understand the different ways to measure things.· Page 4 : 34 Units and Measurements Board & Competitive Exams., , , , The remaining two SI units (Supplementary Units ) and their respective quantities are defined as follows:, , (i) Plane Angle : The angle subtended by an arc of a circle at its centre is called a plane angle., Mathematically it is the ratio of the arc length ds of the circle ... · Page 4 : 34 Units and Measurements Board & Competitive Exams., , , , The remaining two SI units (Supplementary Units ) and their respective quantities are defined as follows:, , (i) Plane Angle : The angle subtended by an arc of a circle at its centre is called a plane angle., Mathematically it is the ratio of the arc length ds of the circle ...
