Question

Reduce 1 law of motion from 2law of motion

Answer 1

The first law of motion can be mathematically stated from the mathematical expression from the second law of motion

F=ma
F= m((v-u)/t)
Ft = mv - mu

When 'F' is equal to 0

Ft = mv - mu
0 = mv - mu
mv = mu
which means, v=u for time 't'

This means that the object will continuemoving with uniform velocity 'v' throughout the time 't'.
If 'u' is 0 then 'v' will also be 0. That is object will remain at rest.
