How to bend it like Beckham?

Apply Bernoulli's principle. The more spin generated on the ball, the more is swerves. This is because the air on one side of the ball has a higher velocity when the ball spins, hence imbalancing the air pressure on either side, thus bending the freekick into the top corner.

Why do you think Lennon, Walcott and Messi run so fast?

It's because their legs are shorter than others. Well, not really, but it does help because the shorter the length of the leg, the shorter its period of oscillation. Meaning they can take more steps in a shorter time than the likes of ordinary people like you and I. Just like the pendulum bob. The shorter the length of the pendulum, the shorter the period for an oscillation.

What's the definition of plasma?

That gooey transparent liquid that oozes out of my wounds when I slide tackle on fields like Grace. It hardens and turns a dark colour, sealing the wound for new skin to form over the cuts. What's best about it? I get to peel off the scabs =D

Define Pascal's principle.

First thoughts would be of players like Pascal Cygan and Pascal Chimbonda. Both defenders, who need to apply equal pressure to every part of the oppositions attack in order to win back the ball. This tactic is called pressing. In physics terms, it means that a pressure applied to an enclosed liquid is transmitted equally throughout the liquid. F1/A1 = F2/A2
