F in the definition of potential energy is the force exerted by the force field, eg, gravity, spring force, etc The potential energy U is equal to the work you must do against that force to move an object from the U=0 reference point to the position rGravitational Potential Energy We know that the magnitude of the gravitational force is given by F = GmM/r 2 Use the connection between force and potential energy to determine the general form of gravitational potential energy U = mgh applies only for a uniform field, so it does not apply here where the field goes as 1/r 2 0 Yes, this equation is what you need!

Scottish scientist William Rankine first coined the term potential energy in the 19th century The equation for calculating the potential energy of a spring is PE = 1/2 * k * x 2, where k is the spring constant and x is the amount of compression The concept of potential energy goes all the way back to Ancient Greece and the philosopher AristotleThe change in gravitational potential energy (ΔPEg) between points A and B is independent of the path The equation ΔPE g = mgh applies for any path that has a change in height of h, not just when the mass is lifted straight up (See Figure 2) It is much easier to calculate mgh (a simple multiplication) than it is to calculate the work doneChemical potential energy is the energy stored in the chemical bonds of a substance The various chemicals that make up gasoline contain a large amount of chemical potential energy that is released when the gasoline is burned in a controlled way in the engine of the car The release of that energy does two things
The measurement of potential energy in an object is calculated based on the object's mass and its height or distance The kinetic energy equation is KE=05 mv^2 where m=mass and v=velocity/speed The potential energy equation is PE=mgh , where m=mass, g= acceleration due to gravity and h=heightPotential Energy Examples Stones sitting on an edge of a cliff possess potential energy If the stones fall the potential energy will be converted to kinetic energy Tree branches high up the tree have potential energy because they can fall to the groundPotential energy is energy that is stored in an object or substance Gravitational energy is a form of potential energy The Earth, the Sun, planets and stars all produce significant amounts of gravity
The work done by a conservative force is equal to the negative of change in potential energy during that process For a proof, imagine two paths 1 and 2, both going from point A to point B The variation of energy for the particle, taking path 1 from A to B and then path 2 backwards from B to A, is 0;About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How works Test new features Press Copyright Contact us CreatorsIt's actually more challenging to come up with ways of generating electricity that are not based on using potential energy But let's see * fossil fuels chemical potential energy obtained from oxygen bonds made when oxidising the fuels * biofu

Gravitational Potential Energy The general expression for gravitational potential energy arises from the law of gravity and is equal to the work done against gravity to bring a mass to a given point in space Because of the inverse square nature of the gravity force, the force approaches zero for large distances, and it makes sense to choose the zero of gravitational potential energy at anElastic potential energy is energy stored as a result of applying a force to deform an elastic object The energy is stored until the force is removed and the object springs back to its original shape, doing work in the process The deformation could involve compressing, stretching or twisting the object Many objects are designed specificallyB Potential Energy C Internal Energy Kinetic Energy A system's kinetic energy is associated with directed motion (eg translation, rotation) of the system Translation refers to straight line motion The kinetic energy Ek of a moving object of mass m and travelling with speed u

Since potential energy is negative in the case of a positive and a negative charge pair, the increase in 1/r makes the potential energy more negative, which is the same as a reduction in potential energy The result from Example 71 may be extended to systems with any arbitrary number of charges In this case, it is most convenient to write theThis is equivalent to its mass times the force of gravity, g (a defined constant of 98 m/s 2) times the height of the object Potential energy = mass x gravity x height Egrav = PE = mgh PE = potential energy, J or kgm 2/s 2 Potential energy is the latent energy in an object at rest, and is one of two forms of energy The other form, kinetic energy, is the energy expressed by an object in motionPotential energy

The amount of potential energy that an object possesses depends on the object's mass or weight, its height above the surface, and the strength of the gravitational field If the other factors are the same, a heavy object will have more gravitational potential energy than a lighter object An object 1 mile (16 km) up in the sky will have more Potential energy is defined as the work which we have to do on the system to bring it into a certain configuration at rest from another configuration at rest in which it has zero potential energy ie in which there are no forces acting If you think in terms of this definition you will know which sign to use, and what the sign meansA typical example is as follows when a ball is held above the ground and released, the potential energy is transformed into kinetic energy Potential energy is that energy which is stored in an object The stored energy varies depending on the types such as physical, chemical or even electrical energy
