The first law of thermodynamics states that energy can be changed from one form to another, but it cannot be created nor destroyed. Any movement you make uses energy proportional to the distance and velocity of your movement. This law of thermodynamics illustrates how important energy is in our everyday lives.
There are two basic types of energy in our world these are kinetic and potential energy. Kinetic energy is the energy objects use to bring themselves into motion in a specific direction. This energy is affected by the environment the object is in, this could either be the size, position, or height of the object. Kinetic energy is the energy that is used when the object moves, which is determined by the object’s stored potential energy.
There are many different types of kinetic energy that we can observe in our everyday lives. These types of kinetic energy will come in the form of electrical, mechanical, radiant, sound, and thermal. Electrical is the kinetic energy free moving electrical ions create. Mechanical refers to the totality of both kinetic and potential energy used in the movement. Radiant is the kinetic energy that is traveling in outer space or a medium. Sound refers to the kinetic energy that comes in the form of audible waves and frequencies. Lastly thermal is the kinetic energy produced due to the collision of atoms when it is in motion. All of these types of kinetic energy can be observed in nature, from the radiant and thermal energy of the lightbulb to the mechanical energy of our arms.
Start by Checking if the object is currently exerting energy. This could be in the form of heat, change in position, emitting light, creating a sound, etc. These are indicators that the object is exerting or emitting kinetic energy.
After completing the first step and checking that the object is exerting kinetic energy, you will now need to identify what is causing the kinetic energy. An example of a kinetic energy source would be the filaments inside the lightbulb, which cause light to appear.
When you have identified the energy source, it is imperative to note down how the produced kinetic energy is presenting itself. Using the example above, the kinetic energy is in the form of the emitted light. This allows you to identify that the light bulb is emitting radiant energy.
Not all things exert only one type of kinetic energy when they do their things, other produce 2 or more types of kinetic energy. You must redo steps 1 to 3 until you have exhausted all the possible kinetic energy the object has exerted. For example, a lit-up lightbulb also produces thermal energy as the area around it and the glass casing is both heated up.
Kinetic energy is the energy used to bring an object into motion either from a resting or a moving position. This could come in the form of the force used to move an object and the object’s innate ability to resist the force; kinetic energy is transferable from one object to another. Potential energy is the object’s stored energy, this is not affected by the size, environment, and height of the object relative to its position. Unlike potential energy, kinetic energy is affected by the size and height of the object relative to its surroundings.
You will need to learn all about kinetic energy, because of its direct interaction with work. Work is the force of an object acting on another object in the same direction as the motion. To understand why objects move in our everyday lives, we will need to understand the basic definition of kinetic energy and how it affects work. You can use the concept of kinetic energy to determine how much force or energy is required to do a certain action.
The formula for kinetic energy is half the mass of the object multiplied by the square of its velocity. The resulting formula is K.E. = 1/2 m v2, which will result in the kinetic energy. (Denoted as Joules or J) You will use this formula to calculate the Joules used by a specific object moving in a direction, which lets people determine the amount of work of a specific action done by an object.
Kinetic energy is an important concept in physics that can explain how things move the way they are. People have used this concept to understand how our human body stores and expends energy.
