SCIENTIFIC FACTS TO REMEMBER NEXT TIME.

-Unbalanced forces means that the object is accelerating not "going forwards"

-remember a=(v-u)/t

-acceleration's units are m/s2

-To independently turn off lamps in a series circuit, make it parallel and add its own switch.

-The cell of a circuit affects its current.

- The law of reflection is: (angle) i = (angle) r

- Diffraction for small gap= lines curve into a semicircle.

  Diffraction for big gap= lines only curve on the ends.
