Approximately 0.01341 horsepower or 0.01 kilowatts.

Power = Work / time= 600 J / 150 secPower = 4 J/s or 4 Watts (1 Watt = 1 J/s)
100
Power = (energy) / (time) =(200 newtons x 4 meters) / (4 seconds) =200 newton-meters per second = 200 watts

Power is measured in watts, or joules per second. So in 90 seconds, 1200 joules of work is equal to 1200/90 watts or 13.3 watts.
10 joules of work in 1 second
The power needed can be calculated using the formula: Power = Energy / Time. Plugging in the given values, the power required to produce 1700 Joules in 5 seconds is 340 Watts.

Work is how much energy is transferred, measured in Joules. Power is how fast or slow the work is transfered, measured in Joules per second. One joule per second is called one Watt of power. This meams a 60 Watt light bulb converts 60 joules of electrical energy into roughly 15 joules of light and 45 Joules of heat every second its switched on for.
The power needed to cut a lawn in 50 minutes, given that the work done is 100,000 joules, can be calculated by dividing the work by the time. 100,000 joules of work in 50 minutes is equivalent to 33.33 watts of power.
Power is the rate at which work is done, and can be calculated as work divided by time. In this case, power = 100 Joules / 10 seconds = 10 watts. Therefore, 100 Joules of work generated 10 watts of power over a 10 second period.
A power output of 25W for one second is 25 joules. It is also 0.03 horsepower (electric motor scale)
Power is calculated using the formula P = W / t, where P is power, W is work done, and t is time taken. In this case, you would calculate power as 648 / 100 = 6.48 watts. Therefore, 6.48 watts of power is needed to do 648 joules of work in 100 seconds.
The power rating of the bulb indicates how much power it uses. The power in watts indicates how much energy in Joules the bulb uses in one second. A bulb should have its voltage and power printed on it.
How fast the energy is provided (power, in joules/second or watts) is irrelevant, as long as not too much energy gets radiated away. What you really need to know is how much energy (in joules) is needed.
Joules (energy) are not equivalent to Watts (power).If something converts 6 Joules every second, it is 6 Watts. If it takes ten seconds to convert 6 Joules, its power is 0.6 Watts.Multiply the Watts by the seconds to find the Joules.CommentYou do not 'consume' power. Power is simply a rate; you cannot consume a rate! You consume energy; the rate at which you consume it is power.
