200 newton-meters per second = 200 watts.
2 to the 2nd power is 4.

To lift a 950-N load 3 meters requires (950 x 3) = 2,850 joules of energy.The power is the rate at which the energy is delivered. It takes more powerto lift the load faster.The power used to lift this load is (2,850 joules) divided by (the number of seconds it takes),and the unit of the answer is watts.
The net output of useful work is (weight) times (gain in height) = 2,000 newton-meters = 2,000 joules.The rate of doing the work, and adding to his gravitational potential energy,is (2,000/40) = 50 joules per second = 50 watts.He certainly had to generate and expend more power than that in order to accomplish the climb.But most of the energy he expended went into heating his muscles and the rest of his body.50 watts is the power that went into the useful part of hoisting his weight to a position of fivemeters higher than where he started.
200 newton-meters per second = 200 watts.
A power of 10 kW or 10,000 watts means that 10,000 Joules of energy is converted every second. In 1 hour the energy expended is 10 kilowatt-hours which would appear as 10 units on the electricity bill.
500N
Thrust: How much power that is being used to go forward. Lift on the other hand: is how much power that is used to gain altitude, like in a rocket ship or a plane.

Power = (energy) / (time) =(200 newtons x 4 meters) / (4 seconds) =200 newton-meters per second = 200 watts

1 kilowatt means a continuous power flow of 1000 watts, and in one hour the energy expended is 1 kilowatt-hour, also known as 1 kWh or Unit.
