Match the following

Work
positive work
negative work
work-energy theorem
work-kinetic energy theorem
mechanical energy
kinetic energy
potential energy
gravitational potential energy
joule
conservative force
non-conservative force.

-energy that is stored in by an object.
-achieved by doing work against the force of gravity.
-the transfer of mechanical energy.
-the energy of motion.
-combination of kinetic and potential energy.
-the special relationship between doing work on an object and
the resulting kinetic energy of the object.
-removes energy from an object.
-when a force does work on an object and the amount of work
done is independent of the path taken.
-when a force does work on an object and the amount of work
done is path-dependent.

mechanical energy-combination of kinetic and potential energy.

positive work-when a force does work on an object and the amount of work
done is independent of the path taken.

kinetic energy-the energy of motion.

negative work-when a force does work on an object and the amount of work
done is path-dependent.

potential energy-achieved by doing work against the force of gravity.

gravitational potential energy-achieved by doing work against the force of gravity.

conservative force-adds energy to an object.

non-conservative force.-removes energy from an object.

work-kinetic energy theorem-the special relationship between doing work on an object
and the resulting kinetic energy of the object

-energy that is stored in by an object( But i don't know what this is T.T)... Can anyone help plz/

You wrote: "potential energy-achieved by doing work against the force of gravity," and "gravitational potential energy-achieved by doing work against the force of gravity." your second answer is correct.

When energy is stored, is it doing something....or does it have the potential to do something?

### rhxoehwhfh

potential energy-
energy that is stored in by an object

right?!

So is everything right ?...

Your answers for conservative force, non-conservative force, positive work, and negative work are incorrect. If you don't have a text with these definitions, I would suggest using wikipedia or some other internet source to find their definitions. People are more likely to remember information if they research it.
