For example, if it takes 60 watts of Power for a machine to fly, yet loses (for instance) 2.5 * 10^3 Joules of its energy because of the air resistance, what's the amount of "Power" that was really given in the first place?
Simon Bridge said:it is not possible to calculate the "real" power without also knowing the time of flight.
So if you lost 2500J in 30mins... How many J in 1sec?tennis38 said:The time of flight is 30 minutes to reach a height of 2230 meters
In physics, power is defined as the rate at which work is done or energy is transferred. It is equal to the amount of work done divided by the time it takes to do the work.
The unit of measurement for power in physics is the watt (W). One watt is equal to one joule per second.
Power can be calculated using the formula P = W/t, where P is power, W is work, and t is time.
Average power is the average rate at which work is done or energy is transferred over a period of time, while instantaneous power is the power at any given moment in time.
Power is the rate at which energy is transferred or work is done. In other words, energy is equal to power multiplied by time. This means that the more power used, the faster energy is transferred or work is done.
