In summary, the problem involves calculating the kinetic energy of an asteroid approaching Earth, assuming it remains intact and ignores the Earth's rotation. The relevant potential energies are found using the equation -GMm/r, with the Earth's mass and radius given. The change in potential ...
In this situation, in which gravity is the only force that is doing work, the energy changes form, but the total energy is a constant value. This is called conservation of energy, and it is a very important concept in physics. It is also important to note, though, that it is true on...

We were able to solve many problems, particularly those involving gravity, more simply using conservation of energy. Those principles and problem-solving strategies apply equally well here. The only change is to place the new expression for potential energy into the conservation of energy e...
Gravitational potential energy is stored energy that exists because objects reside in a gravitational field. For objects on earth the equation is {eq}U_{g}=mgh {/eq}. What the equation really represents is the work done by gravity in placing an object in a certain l...
By the end of this section, you will be able to: Explain gravitational potential energy in terms of work done against gravity. Show that the gravitational potential energy of an object of mass m at height h on Earth is given by PEg = mgh. Show how knowledge of the potential energy as ...
This tool estimates the potential energy on the basis of three values. These are: The mass of the object; Gravitational acceleration, which on Earth amounts to 9.81 m/s29.81 m/s2 or 1 g1 g (the acceleration due to gravity calculator explains why it has such a value); and The height ...
