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.
