You do work on something when you lift it against gravity. how does this work relate to gravitational potential energy? if the lifted object is released, what becomes of this energy? be sure to define all terms that you use.

Increase in the gravitational potential energy will be equal to the work done by us to raise its height.

If the lifted block is released then this gravitational potential energy will convert into kinetic energy of the block.

Explanation:

As we know that work done done to raise the block against the gravity is given as

here force to raise the block will be

now if it is raised to height "h" then work done is given as

so the potential energy stored in the block will be

now when this is released from this height then the potential energy will convert to Kinetic energy of the block as it will drop by the given height.

so we have

i think the answer is a, hope this : )

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
