What is the energy of an object at height?

To summarize, potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.

What happens when the object is lifted to a higher height kinetic energy?

If an object is lifted, work is done against the force of gravity. When work is done energy is transferred to the object and it gains gravitational potential energy. If the object falls from that height, the same amount of work would have to be done by the force of gravity to bring it back to the Earth’s surface.

How does gravitational energy depend on the height H of an object?

The amount of gravitational potential energy an object has depends on mass of the object and height of the object above ground. Objects that are at large height above the ground have more potential energy. Similarly, objects that are at small height above the ground have less potential energy.

How does the height of an object affect its mechanical energy?

Again, the work done on an object in lifting it a height h becomes kinetic energy when that object falls back to its original height. This is simply a mathematical way of saying that the kinetic energy increases as the potential energy decreases, and vice versa.

What is the relationship between energy mass and height?

The gravitational potential energy of an object is the ‘stored energy’ that the object has by being at that height. This is equivalent to its mass times the force of gravity, g (a defined constant of 9.8 m/s2) times the height of the object. Potential energy = mass x gravity x height.

When we lift an object to a height which of the following increases?

An object increases its energy when raised through a height. This is because work is done on it against gravity while it is being raised. The energy present in such an object is the gravitational potential energy.

At which height would an object have the most gravitational potential energy?

A mass 10 m above the ground stores twice as much energy as the same mass only 5 m above the ground. A stronger gravitational pull will also result in more gravitational potential energy. A mass 8 m above the surface of Earth stores much more gravitational potential energy than it would if it were 8 m above the moon.
