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.
