Wrong, it is the integral of momentum with respect to velocity. There I've written it in big so you can absorb the information. Speed is a scalar and not a vector so you wouldn't end up with a scalar but a vector. Energy is a scalar. Schoolboy error John. Still, you can write it in big for cut and paste later. Despite yourself you may actually learn some physics yet.It's speed Jeffrey. You don't end up with negative kinetic energy. Energy is a scalar. Cannonballs do not have less than zero kinetic energy.
Now, do you concede that conservation of energy applies and gravity converts potential energy into kinetic energy and so the relativistic mass of the brick does not increase? Or are you going to persist in promoting bad science?
