4.4 recall and use the relationship: efficiency = useful energy output total energy input
Version 1 Efficiency = Useful Eout / Total Ein x 100 Useful Eout = _Useful_ __Energy_ _Output_ ( J ) Total Ein = __Total__ __Energy_ __Input__ ( J ) Efficiency = Efficiency ( % ) Version 2 Efficiency = Useful Eout / Total Ein Useful Eout = _Useful_ _Energy_ _Output_ ( J ) Total Ein = __Total__ _Energy__ _Input_ ( J ) Efficiency = Efficiency ( _No_ _Units_; a number between 0 and 1 )

Annual Exam
Scientific facts I need to remember to improve:
1. V=d/t
2. State the factor that increases the braking distance.
3. Remember the meaning of the critical angle.
4. 1km= 1000 meters
5. A= v-u/ t
6. Definition of amplitude: Equilibrium to the peak.
