12 wrz 2022 · Calculate average speed. Average speed is distance traveled divided by time of travel. (Take this definition as a given for now. Average speed and other motion concepts are covered in later chapters.) In equation form, $$Average\; speed = \frac{Distance}{Time} \ldotp \nonumber $$
First we calculate the average speed using the given units, then we can get the average speed into the desired units by picking the correct conversion factors and multiplying by them. The correct conversion factors are those that cancel the unwanted units and leave the desired units in their place.

In general, when converting from base units (m, l, g, etc) or derived units (m2,m3, m/s, Hz, N, J, V, etc) to a multiple greater (kilo, mega, giga, or tera) than the base or derived unit- then divide by the factor. For example: 10m = 10/1000km = 1/100 km = .01km. When converting from base units or derived units to a multiple smaller (centi ...
For example, consider a system with E = 5 GeV, p = 4 GeV and m = 3 GeV, which clearly satis-fies E2 = p2 + m2. We can easily convert all quantities to SI units by using the energy conver-sion and c factors: E = 5GeV = 5⋅ ( 1.6 ×10−10 8.0 ×10−10J. p = 4GeV/c = 4⋅ ( 1.6 ×10−10 ) / ( 3×108 2.13×10−18 kg ⋅m/s.
