Propulsion A sauce gravy holder accelerates through the action/reaction pattern (Newtons 3rd Law). You motility irrigate one way with your oar, the gravy holder moves the other way. The impulse (=mass x 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. Figure (1.1) Before the stroke, descend momentum p = 0, since everything is at rest. After the stroke, occur momentum: p = mbvb - mwvw = 0 because the total momentum cant change (Newtons 2nd Law). E.g. for a boat+ conspiracy mass mb = coke kg (i.e. a single sculler) to accelerate from rest to vb = 1 m/s, requires either mw= 10 kg water to be accelerated to vw = 10 m/s, or mw = 20 kg water to vw = 5 m/s, or any other combination of mw and vw that gives th e product mwvw = mbvb = c kg m/s. During the normal stroke (i.e.

with the boat already moving) it is less obvious that water is moved backwards in order to keep the boat moving forwards since the blades displace through to `lock in where they ar placed, but if you look at the puddles when the blades are extracted its clear that water is moved. There has to be close to slippage in order to accelerate the boat, although, from energy considerations (section 3), this should be make as small as possible. So what about if you pushing off the so-and-so of the river, or a series of poles set along the river bank, rather than the water? (I hear you ask).
