Pretty simple stuff

  1. Nov 9, 2007 #1
    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.
    -adds energy to 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?

    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.
