Energy transferred when force causes displacement
W=F×dW = F \times dW=F×d (Force × Distance)
Joules (J) or kilojoules (kJ)
Rate at which work is done
Watts (W) or kilowatts (kW)
P=F×vP = F \times vP=F×v (Force × Velocity)
TcosθT \cos \thetaTcosθ
Driving force equals resistance forces
Always oppose the direction of motion
D=kvnD = kv^nD=kvn where kkk is constant, nnn between 1-2
Driving force equals total resistance forces
KE=12mv2KE = \frac{1}{2}mv^2KE=21mv2
P=WtP = \frac{W}{t}P=tW
