usually a arm would be compared to whatever they were trying to measure.
Primitive units of measurements are fundamental and indivisible units used to quantify physical quantities. Examples include the meter for length, second for time, kilogram for mass, ampere for electric current, kelvin for temperature, mole for amount of substance, and candela for luminous intensity.

mass, length and time are the basic measurement units
(any unit of length or distance) divided by (any unit of time)2 is a unit of acceleration.
the general form of the units for acceleration are distance per time squared, such as m/s2.

Scientists primarily use the International System of Units (SI) for measurements. The SI system is based on seven base units, including meters for length, kilograms for mass, and seconds for time. It provides a consistent and standardized way for scientists to communicate measurements and experimental results.
There are many pieces of evidence as to why PE already existed during primitive time. One of these pieces was the fact that the individuals needed to learn to be strong in order to hunt.
Physical education's existence started during primitive times. the main goal of people then was survival. They go hunting, jumping, galopping, running , climbing and fishing during that time. It is because they need to survive in the hostile environment that they have during that time.
Fundamental and derived measurement units.
Time is not a unit of measurement, but there are measurements that are done in units of time. Examples are seconds, minutes, hours, days, weeks, and years.
