Broadly speaking, all energy in the universe can be categorized as either potential energy or kinetic energy. Potential energy is the energy associated with position, like a ball held up in the air. When you let go of that ball and let it fall, the potential energy converts into kinetic energy, or the energy associated with motion. There are five types of kinetic energy: radiant, thermal, sound, electrical and mechanical. Let's explore several kinetic energy examples to better illustrate these various forms. Radiant Energy ExamplesRadiant energy is a type of kinetic energy, referring to energy that travels by waves or particles. The energy is created through electromagnetic waves and is most commonly experienced by humans in the form of heat. Some examples include:
Thermal EnergyThermal energy is similar to radiant energy in that both can be experienced in the form of heat or warmth. The difference is that while radiant energy refers to waves or particles, thermal energy describes the level of activity among the atoms and molecules in an object. As they move more quickly, they collide more frequently with one another. That motion is why thermal energy is considered an example of kinetic energy, even if you may not be able to see that motion with the naked eye. Some examples include:
Sound EnergyThe human experience of sound is caused by vibrations. The object creating the sound creates waves of movement through a medium, like air, until it reaches our eardrums, which then vibrate and our brain interprets that as sound. Here are some examples of sound energy:
Electrical EnergyElectrical energy, which we more commonly refer to as electricity, is caused by the flow of negatively-charged electrons around a circuit. It is the very movement of these electrons that powers our everyday devices. Here are some examples of electrical energy:
Mechanical EnergyVisually, the most obvious kinetic energy examples are examples of mechanical energy. It is literally the energy associated with the mechanical movement of an object. The more and faster the object moves, the more mechanical energy it has and the more ability it has to do work.
Which is an example of kinetic energy?Kinetic energy is the energy of motion, observable as the movement of an object, particle, or set of particles. Any object in motion is using kinetic energy: a person walking, a thrown baseball, a crumb falling from a table, and a charged particle in an electric field are all examples of kinetic energy at work.
What is the best example of kinetic energy?Anything at home that moves is an example of kinetic energy. This could be a cue ball rolling on a billiards table, a fan circulating air on a warm day, or glass shattering on the floor after it falls from the counter. Electrical devices that are turned on use kinetic energy as do people moving about the house.
Which is an example of kinetic energy quizlet?For example, on a roller coaster when the car is at the top of the hill it has a lot of potential energy (stored energy). When the car moves down the hill, some of the potential energy changes to kinetic energy. Then kinetic energy takes the car back up the hill.
