The correct answer is option 1: Energy supplied per unit time. Power is the rate at which work is done or energy is transferred. It measures how quickly energy is being used or produced. Power is calculated by dividing the amount of energy transferred or work done by the time taken to transfer that energy or complete the work.
Let`s dissect the other options to further understand why they are not correct:
- Option 2 states that power is the energy of an object due to its motion. This is incorrect as power is not solely related to the energy possessed by an object. Power is specifically related to the rate at which energy is being used or transferred, regardless of an object`s motion.
- Option 3 states that power is the energy of an object due to its position. This is also incorrect as power is not solely related to the energy possessed by an object due to its position. Again, power is related to the rate at which energy is being used or transferred, regardless of an object`s position.
- Option 4 states that none of the above options are correct. However, option 1 is indeed the correct definition of power.
In summary, power is defined as the energy supplied or transferred per unit time, measuring the rate at which work is done or energy
