I wanted to ask this question for very long .
lets say we have rocket in mass of 1kg in space that moving in speed of 100 m/s if we want the rocket to speed up, we need to spent some energy that equal to mv^2/2.
in our case it 1*200^2/2 it 2000 Minos the energy we already have which is 100^2*1/2 =5000 .
so the total amount is 20,000-5000 it 15,000 some unit
and if we would like it to speed up from 0m/s to 100m/s we need to spent
1*100^2/ it 5000.
so is it harder to speed up from 100m/s to 200m/s then speeding up from 0m/s to 1000m/s
