How does work change if distance increases?
1 Answer
Explanation:
Considering the definition of Work
Where
Consider you pushing a box on the floor; work represents the energy you have to put in it (ON the system, the box gains kinetic energy)!!! If you maintain the same force but you have to push further...you need to supply more energy!!!
Now consider your box sliding on the floor and you now want to stop it, again using the same amount of force; you are moved across the floor by the box...the box is transferring energy to you doing a work on you (BY the system, you gain kinetic energy) and slowing down. If it pushes you for a longer distance it transfer more energy.
