Okey, lets say we got an object with no start velocity (V_i = 0) which is being pushed by a constant force F, under a certain distance s (during a time intervall dt).(adsbygoogle = window.adsbygoogle || []).push({});

We get through F = ma that

F*s = ma*s = ma*v*dt

We also know that when a is constant (which it is due to the constant force) we got:

a*dt = 2v

which gives us that the work, F*s, equals

2mv^2 instead of (1/2)mv^2

What is wrong?
