Average speed= distance moved/time taken OR Average speed =initial speed +fianl speed/2 1 of 13 Rate of change of speed? Rate of change of speed= final speed-initial speed/time taken 2 of 13 Average velocity? Average velocity= displacement/time....v=d/t OR av. velocity= initial velocity+final velocity/2 3 of 13 Acceleration? Acc.= final velocity-initial velocity/time taken...Acceleration=v-u/t 4 of 13 Resultant force? RF/F= mass x acceleration OR RF/F= m x a 5 of 13 Pressure? Pressure= Force/ area OR P=f/a 6 of 13 Moment? Moment = force x perpendicular distance from the pivot OR moment = f x d 7 of 13 Density? Density= mass/volume OR D=m/v 8 of 13 Efficiency? Efficiency= useful energy output/total energy input. 9 of 13 Work? Work=force x distance OR W=f x d 10 of 13 Power? Power= energy transferred/time taken OR Power= work done/time taken....P=w/t 11 of 13 Kinetic energy? Ke or Ek= mv /2 12 of 13 Potential energy? Pe or Ep= mgh 13 of 13
