It works on a similar principle to how rear wing on a Formula 1 car adds weight, by generating downforce. It's not really weight in the physics sense (mass*gravitational acceleration), but if you had an F1 car on a set of scales while it was generating downforce, it would weigh more without any...

If you think about it, a ball fired vertically upwards doesn't back travel down with additional energy and lands with the same velocity as it had when it was originally fired (opposite direction) assuming no air resistance. With this in mind, its easy to see why they both have the same kinetic...
