The relationship between gravitational potential energy and the mass and height of an object is described by the following equation. A charge placed in an electric field possesses potential energy and is measured by the work done in moving the charge from infinity to that point against the electric field.

Potential energy formula physics. Work is related to energy. G the gravitational field strength 9 81 on earth the formula is relatively simple. An object possesses gravitational potential energy if it is positioned at a height above or below the zero height.
The hardest part is getting your input data. Gravitational potential energy mgh. Rarely is an object raised high enough to change the gravitational field so 9 8 m s2 meters per second squared is almost always used in the formula for potential energy.
Gravitational potential energy is a function of the position of the object in a gravitational field force of gravity at that point and mass of the object. The formula for calculating potential energy even though you are calculating something as complex as potential energy the formula is straightforward. Relative to equilibrium position to summarize potential energy is the energy that is stored in an object due to its position relative to some zero position.
As per the law of conservation of energy since the work done on the object is equal to m g h the energy gained by the object m g h which in this case is the potential energy e. Comparing ke and pe. Kinetic energy ke is amount of energy an object has due to motion.
A better potential energy definition is stored energy and it takes work to store the energy. If two charges q 1 and q 2 are separated by a distance d the e lectric potential energy of the system is. Above is the potential energy formula.
The formula is as follows. To calculate the potential energy of an object the formula for potential energy pe is pe mgh where m stands for mass of the object in kilograms kg g is the gravitational field strength and h is the height of the object in meters m. U 1 4πε o q 1 q 2 d.
G pe m x h. Potential energy gravity m x h x g m mass h h g gravitational field strength on earth it s 9 81 m s. M h g.
It s measured in joules in the si system which are also potential and kinetic energy units. Kinetic energy ke 1 2mass velocity 2 by looking at the above formula we can see that the velocity of the object heavily influences the total ke the object will have. E of an object raised to a height h above the ground m g h.
Physics has a specific definition of work work is done when a force moves an object over a distance. Potential energy is measured in si unit of joule.
