What is power?
the rate of transfer of energy
What is the equation for power?
p = ΔW / Δt = ΔE / t
What are the resistive force when a powered object moves at a constant velocity at constant height?
equal and opposite
What is the equation for power force and velocity?
P = Fv
What happens when a powered object gains speed?
the output force exceed the resistive forces
What is the equation for the motive power?
motive power = energy per second wasted due to resistive force + gain of kinetic energy gained per secoi
