warning to girls & all other physics students. do not attempt to learn physics from peter on the phone. it simply doesn't work.
*adapted from conversation on phone*
peter: right i'll give u a question. a heavy 500 ton ship is moving at... lets say 100km/h. friction is 20N.
lianne: so little?
peter: okay fine, 100.
lianne: so a heavy 500Kg ship...
peter: no!!! 500kg isnt heavy
lianne: sorry, 500 ton ship goes at how fast?
peter: 100km/h.
lianne: friction is 200?
peter: 100
lianne: good. got it. so wat do i have to find?
peter: momentum.
lianne: but it's not crashing into anything!!!
peter: doesnt have to crash into something.
lianne: but..?
peter: okay, make it easier. lianne's fist is 500g and is going at 15m/s.
lianne: (draws a picture of a fish in the water and labels the forces) okay got that. count momentum again?
peter: okay. but air resistance is 1N.
lianne: the fish is in the air?
peter: (thinking he heard fist) obviously? where else do u put ur fist?
lianne: in water?
peter: i said FIST!!! lianne's fist!
lianne: OHH! fist. what i punch with! okay wait let me erase my fish.
peter: you drew a fish?!?
lianne: yea. okay, now fist. but the fish made more sense.
peter: why?
lianne: how can my fist hit the ship?
peter: THIS HAS NOTHING TO DO WITH THE SHIP!!!
lianne: oh. okay. then what does my fist hit?
peter: AAARRRGGGHHHHH!!!
and so on. i was lucky to be able to answer the question after 15 minutes. anyway yea, better continue studying. ta!
