1. What is the principle of moments

  • The head teacher of a specific moment in time
  • anticlockwise moments = clockwise moments. So that there is no net movement/in equilibrium
  • Clockwise added to the anticlockwise moments. So there is no net movement ie in equilibrium
  • anticlockwise moments = anticlockwise moments meaning they're in equilibrium

2. State Ohm's law

  • The current through an ohmic device is directly proportional to the pd across it provided the temperature is constant
  • The current is proportional to the voltage, as long as its kept low
  • Ohm's law is like Murphy's law but different
  • The current through an ohmic device is inversely proportional to the pd provided the temperature is constant

3. what is the conservation of charge

  • the current going into a junction is equal to the current leaving the junction
  • when you turn your phone's battery save on
  • the energy going into a junction is equal to the energy leaving a junction
  • the voltage going into a junction is equal to the energy leaving a junction

4. What is the centre of gravity

  • Where gravity lies in a body
  • Where gravity finds inner peace
  • Where gravitational force acts on a body
  • It's heart

5. What is the conservation of energy

  • When you sip your Redbull instead of gulping it
  • Energy is not lost or gained just transformed into another form
  • Energy is conserved.
  • Energy is not gained but can be lost through heat
