Document Summary
Physical phenomena mostly measured quantitatively using an interval scale: scales require units of measure. Study of how and why physical objects move and/or change shape. Accept the existence of a three-dimensional spatial universe. Distance is the measure of space measured in metres. Planar angle: figure made by two intersecting lines or planes or. = arc (m) / radius (m) angle has no unit, just a measure it is dimensionless: 1 circle = 360 = 2 radians = 1 revolution = 1 cycle. Measures based on portions of a circle: the measure of such a figure. Physical body or substance, occupies space, can be perceived by one or more senses. Volume (v): how much space does a material body occupy: unit litre (l) = a 10 cm x 10 cm x 10 cm cube = 0. 001 m3. Mass (m): how much matter is in a material body: unit 1 kilogram (kg) mass of 1 l of water.
