For gravitational potential energy:
PE = weight x height
PE = mgh (that is, mass x gravity x height)
The first formula is appropriate in this case, since you already know the weight.
Potential energy.
YES!
no, but the POTENTIAL energy may equal the work done to life the book to the shelf
There is no direct relationship because the potential energy of the book on the shelf is defined relative to an arbitrary base line at which the potential energy would be zero. The work done in raising the book is the increase in the potential energy of book from however much PE it had in its previous location - for example, on a lower shelf.
Yes it is. Because it has the POTENTIAL of falling off. Very simple physics, learned that in 6th grade.
0 / 200 = 0 meters.
If the 25N force is directed straight up, so that the force itself moves 1.5 meters tofinish the job, then it does 37.5 joules of work, which becomes 37.5 more joules ofgravitational potential energy that the plant has, once it's on the shelf.
1 joule = 1 newton-meter 800 joules = 800 newton-meters = (200 newtons) x ('H' meters) H = 800 N-m / 200 N = 4 meters

Gravitational potential energy

m=1kg g=9.8 h=1m mgh is the formula for potential energy you IDIOT
Potential energy.
The potential energy of the book on the shelf is equal to the work done to lift the book to the shelf. This is because the potential energy of an object at a certain height is equivalent to the work done against gravity to lift it to that height.
Increased
Use the formula for gravitional potential energy: PE = mgh (mass x gravity x height). Use 9.8 for gravity. Answer will be in Joule.
