  1. You forgot all about the reduced momentum without the added mass of Woodson and Driver in play.

    On a more serious note, the friction coefficient between players cleats and the turf can be a big deal if a team isn't well equipped and has actually cost teams many a rushing yard.

  2. My instinct tells me there wouldnt be significant weather changes from widespread use of wind turbines, but the kinetic energy of the particles in the wind has to go somewhere. Are you prompting that there would be slower windspeeds if turbines were stationed worldwide?

    I would say right away that the density of water has everything to do with it. My common sense is telling me that a denser object would accelerate faster, but of course I'll go look this up. It may also have to do with the fact that water is transparent and snowflakes are opaque. (to relate this fact to physics, we can say that snow reflects photons back to our eyes, while water reflects fewer of these light particles/waves back into our retina). Try tracking a single falling water droplet with your eye sometime; with the right backdrop, its not as hard as you may initially think, at least if you start with your eyes straight ahead. It should be noted however, that in pouring rain the hydrogen bonding dipole forces that occur naturally in water will cause many, many water droplets to merge with each other during their flight, making things much more difficult. And yes, I tracked water droplets for fun as a kid.

    could it be that the change in time for the impulse is made considerable longer by the deformation of the trampoline and then force that results in the upward direction is much less than it otherwise would have been?

  5. Just because you analyzed billiards physics in some way you get five stars. I would say that the orientation of the six billiard balls if they were grouped would usually create different resulting velocities from the initial momentum of the cue ball.

  6. So I read both blogs that have to do with follow through increasing momentum so far, and as an avid badminton player (don't hate on my whiteness) I'm starting to wonder how professionals reach 100 mph speeds with shuttlecocks that have a great amount of drag and if the racket only comes into contact with the shuttlecock a short time.
