Physics 11 F07, Introduction & Mathematical Concepts Measurement, Dimension, and Units All science in general, (and physics in particular) is based on making measurements and drawing conclusions from them about how the world works All scientific theories must be testable by an experiment based upon making measurements.
Physics 11 F07, Introduction & Mathematical Concepts Measurement, Dimension, and Units Heard on NPR (BP sponsorship blurb) … “Energy, it’s more than a force. It’s a power!” To a physicist, this is nonsense. It’s like saying. .. “Apples, they’re more than pears. They’re oranges!” Hopefully, you’ll soon know what’s wrong with this picture.

Physics 11 F07, Introduction & Mathematical Concepts Measurement, Dimension, and Units Dimension refers to the basic nature of a thing we can measure . Basic Physics dimensions are: Mass ([M]) Length ([L]) Time ([T]) (also, Electrical current , Temperature, mole, Luminous intensity ) Other measurable things can be derived from these: Examples: [ speed ] = [L] /[T], [ energy ] = ([M] [L] 2 ) / [T] 2 , [ force ] = ([M][L] ) / [T] 2 [ power ] = ([M][L] 2 ) /[T] 3 , [ area ] = [L] 2 , [ volume ] = [L] 3 Notation: [ something ] means “dimensions of something
