W = fdruss_watters said:"Gravity" is not an equation. What is the mathematical definition (equation) of work?
Great, so can you apply it to this problem?danielsmith123123 said:W = fd
W = Fd -------------- W = (5.6 x 10^10 N) (d) Would "d" be 0 because Planet X keeps orbiting the moon and essentially coming back to where it initially started therefore making it's displacement 0?russ_watters said:Great, so can you apply it to this problem?
Yep, that's one way to look at it - the other is along the direction of motion there is no force. Essentially, the force and displacement have to be in the same direction. Since you don't have that, they'll multiply to zero.danielsmith123123 said:W = Fd -------------- W = (5.6 x 10^10 N) (d) Would "d" be 0 because Planet X keeps orbiting the moon and essentially coming back to where it initially started therefore making it's displacement 0?

Work is the amount of energy transferred when a force is applied over a distance. Power, on the other hand, is the rate at which work is done, or the amount of work done per unit of time.
Energy is the ability to do work or produce change. Work and power are both measures of energy, with work being the total amount of energy transferred and power being the rate at which energy is transferred.
Efficiency is a measure of how well a system or process converts input energy into useful output energy. It is calculated by dividing the useful output energy by the total input energy and multiplying by 100%.
Efficiency can be improved by reducing the amount of wasted energy in a system, such as through insulation or using more efficient equipment. It can also be improved by optimizing the design and operation of a system.
Work, power, energy, and efficiency have many real-world applications, such as in the design and operation of machines and engines, renewable energy systems, and energy-efficient buildings. They are also important in understanding and improving the efficiency of everyday tasks, such as cooking, transportation, and household chores.
