Physics

having used to work in a physics dept at a 6th form college, I used to to a demo about a feather and a ball bearing..obviously wind resistance comes in to it but if you drop a pencil and ball together from the same height, what happens? :wink: ( i dont miss the syrup and honey with different size ball bearings..

maths :D


some rules of maths which i studied few years back :blink:

  1. + x + = +
  2. + x - = -
  3. - x - = +
  4. - x + = -
these will be used for your mathematics question.

I half remember that one

It's to do with the angles of a right angle triangle

Sine =opposite/hypotenuse

Tangent = opposite/adjacent

Cosine = adjacent/hypotenuse

I think this is correct.....it's been 32 years since I did this, and I can't remember what I did 5 minutes ago!!
