Examples of Potential Energy
Potential energy is stored energy from an object. Instead of coming from motion, it can come from its position relative to others, internal stress, electric charge, or its condition. This object has the adequacy of producing energy every bit these conditions change. This energy could be mechanical energy, chemical energy, electric energy, nuclear energy, or magnetic energy.

Mechanical Potential Energy
Mechanical energy is the energy of movement. All items have potential energy based on their position (gravitational potential energy) and power to bounce (rubberband potential energy). When the potential energy of an object is combined with its kinetic energy, it results in mechanical energy.
Examples of Gravitational Potential Energy
When something has a loftier position, its gravitational potential energy is high. For case, a book on a high bookshelf has higher potential energy than a book on the lesser shelf considering information technology has farther to autumn. Other examples of items with gravitational potential energy include:
- A raised weight
- Water that is backside a dam
- A car that is parked at the summit of a hill
- A yoyo earlier it is released
- River h2o at the superlative of a waterfall
- A book on a table before information technology falls
- A kid at the elevation of a slide
- Ripe fruit before it falls
Examples of Rubberband Potential Energy
The fabric an detail is made of tin can affect its potential free energy as well. An elastic ball has higher elasticity than a bowling ball; therefore, it volition bounciness higher with the same amount of force. Here are some more examples of items with elastic potential energy.
- A coiled spring
- An archer’s bow with the string pulled back
- A stretched rubber band
- Soccer balls earlier players kicking them
- A diving lath only before someone dives

Chemical Potential Energy
Chemical energy occurs when free energy is released during a chemical reaction. Potential chemical energy is the energy stored in the bonds of these chemicals, ready to react with some other chemical. Some examples include:
- A charged battery
- Green leaves earlier the sun shines on them (potential photosynthesis)
- Gasoline before it is ignited
- Fireworks earlier they are launched
- Forest in a fireplace before it burns
- Iron earlier it gets moisture and rusts
- Fruit juice before it ferments
- The wick in a candle

Electric Potential Energy
When you come across a light switch that’south off, you lot tin can’t come across the charge that’s waiting to menses through the wires. That’s just one example of electric potential energy. Additional examples include:
- An incandescent low-cal bulb that is turned off
- Your motorcar’s headlights before they are turned on
- A radio belfry that is not working
- A cell telephone that is turned off
- Solar cells at night
- A black low-cal turned off
- A television before it is turned on

Other Forms of Potential Free energy
Nuclear Potential Energy
Nuclear potential energy is stored in the particles of an atom. When the atom is split (in nuclear fission) or atoms are combined (in nuclear fusion), the energy released becomes kinetic energy. Larn more about the uses of nuclear energy.
Magnetic Potential Energy
Like gravitational potential energy, magnetic potential free energy affects how items work based on their position. Items with high magnetic potential energy, such as metal spoons or brawl bearings, respond strongly to a magnetic forcefulness. Objects with lower magnetic potential energy, such as a plastic spoon or a rubber brawl, are non every bit afflicted past a magnetic pull.
Potential Energy and Kinetic Free energy
The laws of physics mandate that most every item has some kind of potential energy. When force is applied to the object, information technology converts to kinetic energy.
Our helpful commodity explains how kinetic free energy appears in the world around us.
