Re: Rules that are [not] getting called at Regionals, the +s and -s
oops, Bob is right. I said kinetic energy, and I used the equation for kinetic energy, but then I referred to the momemtum being the same.
the kinetic energy of a 130 lb robot going 10mph is the same as a 5 lb sledge hammer going 50 mph. Imagine someone taking a wack at the frame of your bot with that sledge hammer at that speed, then decide if you want them to wack the frame, or the bumper with the hammer?
Some other terms I twisted and strained. The frame of your robot will only 'absorb' the energy if the frame is dented in the process. Most of what happens is your robot is accelerated in a very short period of time (milliseconds) to the velocity that is the result of the collision. (this is where the conservation of momentum comes it).
Thats where the damage occurs to the other parts of your robot: the battery holder, the electronics... These parts are not designed to withstand 1000 gs of acceleration, not even for a short period of time, so components and screws and bolts start breaking.
