OUCH!!!!
Just to be clear, an object's mass does not increase with velocity (not unless it is going really, really fast, like approaching the speed of light).

It's momentum and the force that it would apply on another object does increase with velocity however. In this case, the weight (which is a measurement of force) that a scale reads when you jump on it.
