<fzabkar@xxxxxxxxxxxxxxxxx> put finger to keyboard and composed:
The impulse energy is defined by ...
E = F.dt = m.a.dt
where F = force, a = acceleration, m = mass, dt = impulse duration
Brain fart!
F.dt = m.a.dt = m.dv/dt.dt = m.dv
ie F.dt does not have the units of energy. It in fact represents a
change in momentum.
