<span>No machine can operate at 100 percent efficiency because some of the energy input will always be used to overcome the force of gravity and the effects of friction and air resistance.</span>
Answer:
Air resistance
Explanation:
Despite the law of conservation of energy stating that energy can neither be created nor destroyed but can only be transformed from one state to another, some energy is usually lost in the process of transformation and its majorly attributed to frictional loss. Friction opposes normal movement hence in air, air resistance tends to reduce the original energy compared to the initial. That is why the final energy in this case is slightly less than the original energy.
It creates friction on the forward moving object, causing it to loose momentum, until finally, it stops.
Hope this helps!
Against due to the fact that they grow up and gravity goes down.
Answer:
because potentil energy is redy to go but its bound up
And kinetic energy is in motion
Explanation:
