Nobody has told you here so remember:
mass X acceleration is force so kg m/s^2 = N
mass X velocity is momentum so kg m/s = ?
Watch out for it being called Ns which has the same unit but is some thing completely different
Force X distance = N X m = kg m^2/s^2 = WORK = Joule (J)
Heat, energy, work are all in J which should tell you a lot.
Power =Watt (W) = W = J/s = N m /s = kg m^2/s^3
This is all part of what is called unit analysis, or you can't get the problem right if the units are not right. Its part of getting the paperwork done. Plus, if you learn the units you can usually figure out how to work out the answer based on the data given you in a problem.

Nope. In fact, it's not any power at all. It's force, and it's a pretty small force at that.
To calculate how small:
1 newton is the force required to give 1kg of mass an acceleration of 1m/s^2. The acceleration of gravity (on Earth, near the surface) is about 9.81 m/s^2, so 1kg weighs about 9.81 newtons. In US common measure, 1kg weighs slightly over 2.20 lbs., which is about 35.4 ounces. (Avoirdupois, if anyone cares)
So, calculate (35.4 oz/kg)*(0.127 nt)/(9.81 nt/kg) and you get about 0.458 oz., or just under half an ounce.

Well Newtons is a force not a pound. And 0.127 N isn't really that much force. But its all relative.
