CHAPTER 8 If a potential energy can be associated with a force, we call the force conservative. Examples of conservative forces are the spring force and the gravitational force. If a potential energy can not be associated with a force, we call that force non-conservative. An example is the friction force.

Potential Energy with Examples The energy of the objects due to their positions with respect to the ground is called gravitational potential energy. The pictures given above are the examples of gravitational potential energy. They both have a height from the ground and because of their positions they have energy or potential to do work.

Gravitational Potential Energy This energy was stored as potential energy in the gravitational field of the Earth and came out of storage as the water dropped. This energy which came out of the gravitational field ended up being expressed as the kinetic energy of the water. That is, the water gains kinetic energy as it drops. An ounce of water is going faster when it hits the bottom of the waterfall than it was when it went over the top of the waterfall. Energy that is stored in the gravitational field is called gravitational potential energy, or potential energy due to gravity. Let's see how energy gets stored in the gravitational field. The above formula for work shows a dot product for the multiplication of the force vector times the displacement vector.

Explain the difference between Kinetic Potential Energy and Gravitational Potential Energy. Use examples to? Any object which is moving relative to you, will have kinetic energy. An example would be a bullet fired from a gun. Gravitational potential energy occurs when something is lifted up above some reference point (ie the ground). After it is lifted, it can be dropped, at which point it's potential energy will turn into kinetic energy as it speeds up. An example would be water at the top of a waterfall. Source(s):

- Gravitational potential energy is energy an object possesses because of its position in a gravitational field. The most common use of gravitational potential energy is for an object near the surface of the Earth where the gravitational acceleration can be assumed to be constant at about 9.8 m/s 2.

Potential Energy Gravitational potential energy is the energy stored in an object as the result of its vertical position or height. The energy is stored as the result of the gravitational attraction of the Earth for the object.

- The amount of gravitational potential energy is dependent on both the weight of the object and its position, or height, above the ground. Since the counterweight in a trebuchet is very heavy, it has a great deal of potential energy. While energy cannot be created or destroyed, it can change forms.

- Types of Potential Energy. 1  Potential energy is a type of energy that is hidden in some way. It is a type of energy that can be converted to other forms and often is related to some attractive or pushing forces.  Anything that can act like a spring or a rubber band can have elastic potential energy.

Potential Energy The equation is. To summarize, potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.

Hooke's law The potential energy of a spring () is sometimes called elastic energy, because it results from the spring being stretched or compressed. Mathematically, is defined by: The potential energy of a spring is greatest when the coil is maximally compressed or stretched, and is zero at the equilibrium position.

Potential Energy Potential Energy: Potential energy exists whenever an object which has mass has a position within a force field. The most everyday example of this is the position of objects in the earth's gravitational field. The potential energy of an object in this case is given by the relation: PE = mgh . where PE = Energy (in Joules) m = mass (in kilograms)

Potential energy Common types include the gravitational potential energy of an object that depends on its mass and its distance from the center of mass of another object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field.

- Definition of Gravitational Potential Energy (PE): it is the stored energy in an object by virtue of the object's position in the gravitational field (height above the ground). Equation for PE: PE = mass x acceleration due to gravity x height above the ground. or PE = mgh. Units of PE: kg-m^2/s^2 = N-m = Joules.et's say that a 1 kg object is lifted up at constant speed to a height of 5 meters. Using 10 m/s^2 for g, this would mean that we used (1kg)(10 m/s^2)(5 m) or 50 J of work. This is stored as gravitational potential energy.

Gravitational Potential Energy As it falls its height above ground gets less and less, so, the potential energy stored in gravity gets less and less, also. The object, though, is speeding up as it falls. Energy is leaving the gravitational field and entering the falling object as kinetic energy. Kinetic energy is the energy of motion.

What is elastic potential energy? Nowadays, we don't tend to use wind-up smartphones because no materials exist with high enough elastic limit to store elastic potential energy with high enough energy density. The energy density of a coiled steel spring is about 8 kJ/kg, whereas a lithium-ion battery has an energy density of around 500 kJ/kg [1].

Spring Potential Energy (Elastic Potential Energy) This last formula reads: The potential energy of a spring, or the energy stored in a spring, equals one half times the spring constant times the square of the extension. This is how to calculate how much energy is stored in a spring.

Gravitational Potential Energy The water above receives energy as it falls down the short waterfall. This energy was stored as potential energy in the gravitational field of the Earth and came out of storage as the water dropped. This energy which came out of the gravitational field ended up being expressed as the kinetic energy of the water.

Examples of Potential Energy and Kinetic Energy Lets stretch a rubber band, it will gain potential energy. The more we stretch it the rubber band gains more potential energy. When it is released, potential energy gives out the motion. So here Potential energy gets converted into Kinetic energy. Lets take an archery illustration.The archer stretches the string and then releases the arrow towards the target.Here the stretched bow possesses kinetic energy that gets converted into kinetic energy once the arrow is released. Hence the potential energy gets converted to kinetic energy.

Electric Potential Energy For example, if a positive charge Q is fixed at some point in space, any other positive charge which is brought close to it will experience a repulsive force and will therefore have potential energy. The potential energy of a test charge q in the vicinity of this source charge will be:

Potential Energy When the object is at rest at some height, h, then all of its energy is PE. As the object falls and accelerates due to the earth's gravity, PE is converted into KE. When the object strikes the ground, h=0 so that PE=0, the all of the energy has to be in the form of KE and the object is moving it at its maximum velocity. (In this case we are ignoring air resistance).

Electric Potential Energy Electric Potential Energy. Potential energy can be defined as the capacity for doing work which arises from position or configuration. In the electrical case, a charge will exert a force on any other charge and potential energy arises from any collection of charges. For example, if a positive charge Q is fixed at some point in space, any other positive charge which is brought close to it will experience a repulsive force and will therefore have potential energy.
