Since the force required to lift it is equal to its weight, it follows that the gravitational potential energy is equal to its weight times the height to which it is lifted. PE = kg x 9.8 m/s2 x m = joules. PE = lbs x ft = ft lb.

Types of potential energy include:

• Gravitational potential energy.
• Chemical energy.
• Nuclear energy.
• Elastic potential energy, also called spring energy.
• Electrical potential energy especially in a capacitor.

Gravitational Potential Energy is determined by three factors: mass, gravity, and height. All three factors are directly proportional to energy.

Gravitational potential energy is usually given the symbol U g U_g Ug​U, start subscript, g, end subscript. It represents the potential an object has to do work as a result of being located at a particular position in a gravitational field.

Like energy, it is a scalar quantity, with SI units of joules. Heat conduction is not considered to be a form of work, since there is no macroscopically measurable force, only microscopic forces occurring in atomic collisions. The term work was created in the 1830s by the French mathematician Gaspard-Gustave Coriolis.

Zero work is defined when force and displacement are perpendicular to one another and when force or displacement is zero. Example: The force acts in a downward direction, When displacement operates in the forward direction. If you push a wall, it doesn’t move there’s no work done.

The angle theta in the equation is the angle between F and d. If the F is parallel to the incline and the d is parallel to the incline, then the angle theta in the work equation is 0 degrees. For this reason, W=F*d*cosine 0 degrees. In each case, the work is approximately 1.18 x106 Joules.

Energy transformation

There are five types of kinetic energy: radiant, thermal, sound, electrical and mechanical.

Potential energy is the stored energy an object has because of its position or state. A bicycle on top of a hill, a book held over your head, and a stretched spring all have potential energy.

Potential energy is energy that an object stores. It is the energy that an object possesses when it is not in motion. As a moving object slows down, its potential energy increases. As the object speeds up, its potential energy decreases.

A vibrating pendulum when it is just passing through its mean position is not the example of potential energy.

A non-example would be a word that is not an example of a bird. It is important to come up with non-examples that are related to the word, but that are not examples of the word.

Examples provide synonyms or other means of similarity with the unclear concept. Therefore, an example is always like or similar to whatever it is an example of. Nonexamples are, as you can tell, the opposite of examples. Where examples provide an instance of similarity, nonexamples provide an instance of contrast.

A person who is not an inhabitant or national of a particular state or town. ‘most of the refugees were classed as non-citizens’ More example sentences. ‘The legislation would likely end up applying to all non-citizens detained by the government both outside the US and within. ‘

Unlike counterexamples, non-examples aren’t necessarily used to describe the opposite of a concept….Notes.

Non Example of Gravity. – a kite is flying in the sky due to wind pushing it up. – helium filled balloon floating upwards.

Nonverbal communication refers to gestures, facial expressions, tone of voice, eye contact (or lack thereof), body language, posture, and other ways people can communicate without using language.
