所以虽然最终的s=0 但total workdone 也不是0.No the wer is zero since in the equation W=Fs. s is the displacement. So in your case the displacement is zero so there will no work done. Your wer is the energy used not work done.

Work and Energy:As is known, the environment is able to transmit energy to an element by the action of a force over a distance (mechanical work), which causes the acceleration (or deceleration) of the element; in short, a force is able to change its kinetic energy....
Let us start by considering the total, or net, work done on a system. Net work is defined to be the sum of work done by all external forces—that is,net workis the work done by the net external forceFnet. In equation form, this isWnet=Fnetdcosθwhereθis the angle between the ...
As the train moves up the incline, it gains potential energy, which can be calculated using the equation "Potential Energy = Mass * Gravity * Height." Putting all of this together, the work done by the engine can be calculated using the following steps: 1. Convert the train's mass from...
From equation (ii), it is clear that the work done by a force on an object is equal to the change in kinetic energy of the object.FAQs on Derivation of Work Energy Theorem 1. Why is the Work-Energy Theorem important for the students to learn? Work-Energy Theorem is basically a really...
atherefore no energy equation was solved. Mass transfer between phases and chemical reactions were neglected. As mentioned earlier, the interphases drag forces would mainly dominate the motion of bubbles and themagnitude of lift force is much smaller than the interphases drag force. Considering this,...
