As the car begins to roll down the hill, it loses potential energy, but gains kinetic energy. Yet when its position is altered from its usual equilibrium position, the bow is able to store energy by virtue of its position. Thus the energy stored from sunlight is converted to chemical energy and then used to keep the life on earth. Intermolecular Potential Energy This type of potential energy is one which depends on the magnitude of the forces of attraction or repulsion within the molecules of a substance as well as the relative position of the molecules. Potential energy is the energy possessed by a body by virtue of its position or state. Retrieved on May 31, 2017, from softschools. The kinetic energy that is formed in this process is very useful or dangerous at the same time.

Examples of forces that have potential energies are gravity and spring forces. On an atomic scale, the collected energy is a temporary pressure placed on the connections between atoms, and that means that there is no permanent modification of the material. If the needle is moved by an outside force, torque is exerted on the magnetic dipole of the needle by the Earth's magnetic field, causing it to move back into alignment. In the case of a , when the archer does work on the bow, drawing the string back, some of the chemical energy of the archer's body is transformed into elastic potential energy in the bent limb of the bow. When a spring is stretched out farther there is more potential energy, and when a spring is stretched out a little bit, it does not have as much potential energy.

When the string is released, the force between the string and the arrow does work on the arrow. Typically the potential energy of a system depends on the relative positions of its components only, so the reference state can also be expressed in terms of relative positions. It arises as a consequence of a force that tries to restore the object to its original shape, which is most often the between the atoms and molecules that constitute the object. An object possesses elastic potential energy if it is at a position on an elastic medium other than the equilibrium position. Based on its nature and character, it is of different types.

This is the principle used in batteries to generate energy. To start with, energy in Physics is referred to as the ability to do work. To raise the book from the floor to the table, work must be done, and energy supplied. Kinetic energy gained remains constant while in orbit. This type of potential energy is effective on any object with mass that is in a gravitational field. It can be said that potential energy is kinetic energy in the making.

An example would be a stretched rubber band or a spring. An object possesses gravitational potential energy if it is positioned at a height above or below the zero height. To stretch the rubber band you have to use energy. Fact 19: A car on a top of the hill has the most potential energy. A typical example is as follows: when a ball is held above the ground and released, the potential energy is transformed into kinetic energy.

This energy is very useful for human activities like in transport, electricity generation, cooking, molding of tough metals, etc. It is dependent on the mass of the object, the height of the object above the ground or Earth, and the acceleration due to gravity. The release is often due to some chemical interactions between the various chemical elements of the substance possessing this type of potential energy. In the Sun, the process of hydrogen fusion converts about 4 million tonnes of solar matter per second into , which is radiated into space. Examples of elastic potential energy include springs, rubber bands, and slingshots. Example problems: What is the potential energy of a 2 kg rock sitting at the top of a 10 meter high cliff? Nuclear Potential Energy It is a type of potential energy associated with particles such as: protons and neutrons, within the nucleus of an atom.

Since the work of potential forces acting on a body that moves from a start to an end position is determined only by these two positions, and does not depend on the trajectory of the body, there is a function known as potential that can be evaluated at the two positions to determine this work. For example, a lightning strike can convert electrical energy into light energy, thermal energy, and sound energy. This type of energy is present in every object which has a mass and position within a force field and has a kinetic energy of zero relative to other objects. It takes more energy to break a strong bond than a weak bond. Check Your Understanding Check your understanding of the concept of potential energy by answering the following questions. Fact 14: The name potential energy is because there is a potential for using stored energy. Physics for Scientists and Engineers 8th ed.
