11P Science

If your brain is anything like mine you are starting to go into a kind of daze now when I put equations on the board. When I was at school I never really understood what the equations meant or when I was supposed to use them… What I did know was that distance was measured in metres, time was measured in seconds and speed (or velocity) was measured in metres/second. So you could say I knew the units of what I was trying to find out. So I would find an equation that gave me the units of what I was looking for, and see if I could combine the numbers I got in the question using that equation. Its a pretty cack-handed way of going about things now I look at it, but it was successful enough.Learning that “I” stood  for current, which was measured in Amps would have been a huge leap forward when I was 15…Hope you are all having a lovely evening, remember to study for the car test
