What is potential energy?Potential power is the save on computer energy an object has because of its position or state. A bike on top of a hill, a publication held over your head, and a extended spring all have actually potential energy.

You are watching: The motion of a rock rolling downhill is known as __________ energy.

How to measure up Potential EnergyThe conventional unit because that measuring potential power is the joule, which is abbreviated together "J."How is it different from kinetic energy?Potential power is stored power while kinetic power is the power of motion. When potential power is provided it is converted into kinetic energy. You deserve to think that potential power as kinetic energy waiting come happen.
The green ball has actually potential energy due to its height. The violet ball has kinetic energy as result of its velocity.
A vehicle on a HillWe can compare potential and kinetic energy by considering a vehicle on a hill. When the auto is in ~ the optimal of the hill it has the most potential energy. If that is sit still, it has no kinetic energy. As the automobile begins to roll down the hill, it loses potential energy, however gains kinetic energy. The potential energy of the place of the vehicle at the top of the hill is obtaining converted into kinetic energy.
Gravitational Potential EnergyOne kind of potential energy comes from the Earth"s gravity. This is referred to as gravitational potential power (GPE). Gravitational potential energy is the power stored in an object based on its height and also mass. To calculation the gravitational potential energy we use the adhering to equation:
Where "g" is the typical acceleration of heaviness which equals 9.8 m/s2. The height is determined based upon the height the object could potentially fall. The elevation may be the distance over the soil or maybe the rap table we space working on.Example problems:What is the potential power of a 2 kg absent sitting at the height of a 10 meter high cliff?GPE = fixed * g * heightGPE = 2kg * 9.8 m/s2 * 10mGPE = 196 JPotential Energy and also WorkThe potential energy is equal to the lot of work-related done to get an object into the position. For example, if you were to background a publication off the floor and place that on a table. The potential energy of the publication on the table will certainly equal the amount of occupational it took to move the publication from the floor come the table.Other species of Potential EnergyElastic - Elastic potential power is stored when materials stretch or compress. Instances of elastic potential energy include springs, rubber bands, and slingshots.Nuclear - The potential power of the particles inside an atom.
Interesting Facts around Potential EnergyScottish scientist wilhelm Rankine very first coined the term potential energy in the 19th century.The equation because that calculating the potential energy of a feather is PE = 1/2 * k * x2, wherein k is the spring consistent and x is the lot of compression.
