Answer:The SI unit of force is the newton, symbol N. The base units relevant to force are:
The metre, unit of length — symbol m
The kilogram, unit of mass — symbol kg
The second, unit of time — symbol s
Explanation:Force is defined as the rate of change of momentum. For an unchanging mass, this is equivalent to mass x acceleration.
So, 1 N = 1 kg m s-2, or 1 kg m/s2.
