Place it at a higher altitude, wind it up, fill it with fuel, etc.
potential energy
Kinematics
When you lift an object, the energy transferred to the object is called gravitational potential energy.
A object falling form a height, h. At h it has graventational potential energy and when it starts to fall this energy tranferes into kenetic.ability toput mass of any sort into a motion of accelleration therefore resulting in having potential of producing kenetic energy into said mass
Also double since potential energy is the energy stored in a body due it's position.
That is called potential energy.
The gravitational potential energy does not change if the desk is horizontal. The work done is in overcoming the friction between the object and the desk.
An object gets gravitational potential energy by
I assume you mean the gravitational potential energy. This is proportional to the mass, so if you change the mass by a factor of "a", the gravitational potential energy will change by the same factor of "a".
more often than not, potential energy is calculated, not measured, based on which means of energy conversion you are looking for. Potential energy released by falling is not the same as potential energy of a nuclear reaction, although the same object can do both
When an object falls down, potential energy is converted to kinetic energy.
If an object falls down, potential energy will be converted into kinetic energy (energy of movement). However, if an object drifts down slowly - say, a feather falling in air, or an object that falls down in water - the energy will be immediately converted to heat energy.
