Homework Help: Potenital Energy

  1. Jan 15, 2004 #1
    If a 1000 kilogram car is lifted 1 meter what is its potential energy
    with respect to the floor?

    I used the following to solve,
    PE = mgh

    1000 * 1 + 1000PE

    Is this the correct formula for solving for PE.

    I am confused with the relationship potential energy and height.

    The higher you lift a mass, the more gravitational potential energy you have.

    Your answer is incorrect.

    You start correctly with PE = mgh.

    m = mass
    g = acceleration due to gravity (9.8 m/s^2)
    h = height.

    All you need to do is plug the numbers you have into the equation.

    thanks I feel a sleep on the job, again.
