What Are Examples of Potential and Kinetic Energy?

• 1) Planets. The movement of planets around the sun and other stars in the galaxy is kinetic energy at work.
• 2) Rubber Bands. Rubber bands can be classified as both potential and kinetic energy, depending on the state of the band.
• 3) Rivers.
• 4) Specific Variations.

13 Examples of Kinetic Energy in Everyday Life

• Hydropower Plants. Hydropower plants are places where the generation of electricity takes place with the help of water.
• Wind Mills.
• Moving Car.
• Bullet From a Gun.
• Flying Airplane.
• Walking & Running.
• Cycling.
• Rollercoasters.

Potential energy is the stored energy in any object or system by virtue of its position or arrangement of parts. However, it isn’t affected by the environment outside of the object or system, such as air or height. On the other hand, kinetic energy is the energy of an object or a system’s particles in motion.

A molecule of glucose is an example of potential rather than kinetic energy.

An object can store energy as the result of its position. For example, the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly, a drawn bow is able to store energy as the result of its position.

The sugar glucose, for example, is high in potential energy. Cells degrade glucose continuously, and the energy released when glucose is metabolized is harnessed to do many kinds of work. A second biologically important form of potential energy, to which we shall refer often, is the energy in a concentration gradient.

Potential 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 ground. The food that we eat has chemical potential energy.

In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors….

Equations

Gravitational potential energy is negative at the surface of Earth, because work is done by the gravitational field in bringing a mass from infinity i.e work has to be done on a body, if it is taken away from the gravitational field of the earth. Thus, potential energy is negative.

The gravitational potential energy has the same units as kinetic energy, kg m2 / s2. In fact, all energy has the same units, kg m2 / s2, and is measured using the SI unit is Joule (J).

In equation form: work (joules) = force (newtons) x distance (meters), One joule is defined as the amount of work done when a force of one newton is exerted through a distance of one meter.

U is the letter most similar to V – there are lots of times when, if V is used as a variable for a concept, then U is a variable for a similar concept. So potential energy became U, because someone might have been trying to make a connection with potential voltage.

The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

entropy, the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. Because work is obtained from ordered molecular motion, the amount of entropy is also a measure of the molecular disorder, or randomness, of a system.

A campfire is an example of entropy. The solid wood burns and becomes ash, smoke and gases, all of which spread energy outwards more easily than the solid fuel. Ice melting, salt or sugar dissolving, making popcorn and boiling water for tea are processes with increasing entropy in your kitchen.

Entropy is basically the number of ways a system can be rearranged and have the same energy. Chaos implies an exponential dependence on initial conditions. Colloquially they can both mean “disorder” but in physics they have different meanings.
