Physics made fun! Learn about physical quantities and measurements
play_arrow0:06 In physics, every measurement of data taken is comprised of two components
play_arrow0:28 Therefore, when measuring data, we use specific instruments to find out the size of the reading in relation to the units found on the instrument
play_arrow0:55 The type of instrument we use to make readings is important as it can alter the units of a value
