The Science of Baseball

At the WSU Sports Science Lab, a team of engineers tests out all kinds of baseballs and bats. In the lab, canons send baseballs flying up to 585 mph. That’s nearly five times faster than the fastest human pitch on record.

They use their expert knowledge on energy, force, and speed to find out what happens when a bat and ball collide. They measure how the equipment performs and make sure the equipment is safe for athletes to use during the game.

You could be an engineer one day, too. Stay tuned for more from the Sports Science Lab. In the meantime, check out videos from the lab on their » More …
