One of the fundamental laws of motion states that the acceleration of an object is directly proportional to the resultant force on it and inversely proportional to its mass. From this statement, determine the dimensions of force.

Whats the answer?

The law sets up the proportion:
a = kF/m Where k is some constant (no units)
This can be rearranged to:
kF = ma
From this equation we can clearly see that the units of force are:
Kg m/s^2

Force = Mass (kg) x Acceleration due to gravity (9.81m/sÂ²)
= N (Newtons force. (Weight)).
So...Force (N) = mg
Therefore,... m = N/g and g = N/m
