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.

 

[rhxoehwhfh]

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 please/

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.
