one thing i love about having not enough free time is the fact that i have to literally run everywhere. which is probably the reason i do cross country and track, however these guys must really be in a hurry. when i'm late for a class i usually just take the stairs, these guys jump out of a window. the amazing examples of projectile motion exhibited here are.... well, cool.
when jumping out of a window or off the top of a building the x velocity they have at the moment of jumping is the same throughout their flight but the y velocity is what is affected by gravity. in most of these clips they are merely falling off of what ever they jump from, but in a few we can see them move vertically by having a velocity great enough to momentarily escape the -9.8 m/s2 and fly upwards long enough for the force of gravity to not make them move in a negative direction.
there are also many good examples of momentum and rotational force throughout these videos but i do not know enough about that to properly explain them.
