### 8.5.Conservation of the Quantity of stimulus and decisions

Go forward =>
A body with M mass will be constituted by a multiple m of i mass units, each one of them capable of making decisions.
A body with M' mass will be constituted by a multiple m' of i mass units.
Let's imagine that,

M > M'

In this case, the number of stimulus that M sends to M' are more than the number of i units that can make a decision. According to the Second Law, that means some of the body M'´ s units will have to make two or more decisions in order for the M body's stimulus to have an answer from M´ body.
On the other hand, in the case of a body with M mass, in order for all the units that constitute it to receive a stimulus and have a decision it'll be needed a longer period of time, that means the answer given by M as a body will be generated more slowly.
The more units the body has, the longer time we'll need in order for all of them to answer and also for an answer from the body to be generated.
Let's consider a body with m mass, generating stimulus at a v speed on a m' mass body that generates decisions at a v' speed.
According to the Second and Third Laws, we will always find that

m.v=m'v'
