In summary, the gravitational potential energy of a 1000 kilogram car lifted 1 meter above the floor can be calculated using the formula PE = mgh, where m is the mass of the car, g is the acceleration due to gravity (9.8 m/s^2), and h is the height. Simply plug in the values and solve for PE. The relationship between potential energy and height is that the higher a mass is lifted, the more potential energy it has.

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.

What is potential energy?

Potential energy is the energy that an object possesses due to its position or condition. It is stored energy that has the potential to do work.

How is the potential energy of a 1000 kg car at 1m height calculated?

The potential energy of an object is calculated by multiplying its mass (m) by the acceleration due to gravity (g) and its height (h). In this case, the potential energy of the 1000 kg car at 1m height would be mgh, which equals 1000 kg x 9.8 m/s^2 x 1 m = 9800 joules.

What is the unit of measurement for potential energy?

The unit of measurement for potential energy is joules (J).

Does potential energy change when the height or mass of an object changes?

Yes, potential energy is directly proportional to the height and mass of an object. As the height or mass increases, so does the potential energy, and vice versa.

How is potential energy related to kinetic energy?

Potential energy and kinetic energy are two forms of mechanical energy. Potential energy can be converted into kinetic energy, and vice versa, as an object moves from a higher position to a lower position. In the case of the 1000 kg car, as it moves from 1m height to the ground, its potential energy decreases and its kinetic energy increases.
