Energy transferred when force causes displacement
W=FimesdW = F imes dW=Fimesd (Force × Distance)
Joules (J) or kilojoules (kJ)
Rate at which work is done
Watts (W) or kilowatts (kW)
P=FimesvP = F imes vP=Fimesv (Power = Force × Velocity)
P = rac{W}{t} (Power = Work / Time)
They increase as speed increases
D=kvnD = kv^nD=kvn where nnn is typically between 1 and 2
D=kv2D = kv^2D=kv2
Driving force = Resistance forces
Driving force equals total resistance forces
KE = rac{1}{2}mv^2
