Sports Watch Play

IceIceBaby asked:


I already know a few things about why they have to do with science, when I say science I’m talking about Mechanical Advantage and Efficiency, things like velocity, levers(first class,second class, third class), friction, simple machines(pulley, gear,wheel etc…) and many more. Anyway, here are the sports:

Diving (diving board- second class lever)
Hockey (hockey stick-third class lever)
Biking ( friction and wind resistance)
Running (friction or traction)
Tennis (racket-third class lever)

Please use some scientific words, but easy enough for me to understand. Also, explain how and why they have to do with science.

I am a 13 year old girl who is seventh grade and I will be going into eighth grade next summer. I play volleyball in the fall, basketball in the winter, and softball in the spring. I want to know how to be good at all of these sports! Well, not good but great! If you are only an expert on one of these sports don’t feel like you have to answer for all of the questions! Thanks in advance!

I have a couple of sports cards that I have collected over the years that I know are limited runs or autographs of good players and rookies. I would like to get these graded by a major sports card grading company such as Beckett or Profession Sports Authenticator (PSA). If you have any information about the cost and how to go about it that would be great.

I am trying to build a profile of the type of person who would book corporate sports hospitality packages. Who would they be entertaining?

Have you ever been invited to hospitality at a sports event? Who invited you?
