Physics of rowing
Propulsion
A boat accelerates through the action/reaction principle (Newton's third law). You move water one way with your oar; the boat moves the other way. The momentum (=mass*velocity) you put into the water will be equal and opposite to the momentum acquired by the boat.
Consider a boat before and after a stroke.
PIC 1
Before the stroke, total momentum p = 0, since everything is at rest.
After the stroke,

to be little agreement on definitions of work and power in the rowing biomechanics literature. Dal Monte and Komor (1989) present a table summarising some of those that have been used and there are seven definitions of work and twelve definitions of power! In the present study, we define the useful work done to overcome the total resistance on the hull and rowers during a stroke as
PIC 18!!!!!!!!!!!!!!!!!!!!!!
The mean power during the stroke is
PIC 19!!!!!!!!!!!!!!!!!!!!!!!!!
