Storyboard Text

  • We should have a competition comparing our work and power during the swim!
  • Not just a race??
  • No, a race would just measure our speed. Work is force x distance. This is a 50 meter pool...
  • Right, so I'll be doing 17,650 N of work. You'll be doing 22,075 N of work.
  • If I weigh 45 kg and you weigh 36 kg, your force is about 353 and mine is 441.5.
  • Not so fast! We still have to swim. When we divide work by time we find the power.
  • So I win?!?
  • My time was 48 s, so my power was 367 J
  • We tied!
  • Mine was 60 s, so my power was...about 367 J, too!
