      Examples of Kinetic Energy

      Kinetic energy is the energy of motion. It is also referred to as energy in motion, or as the work required to take an object from being at rest to action/movement. Mathematically, kinetic energy is calculated as ½ of the mass of a body, multiplied by the speed of the body squared, KE=1/2 mv^2. Where

    • Perigee

      Perigee

      Perigee is a term used to describe the closest point at which an object orbits the Earth or another object in space. When an object is at its perigee, it travels faster than it does at any other point in its orbit because it is under the influence of the strongest gravitational force that its

    • What Causes Evaporation?

      What Causes Evaporation?

      When the Earth begins to get too hot, the water increases in temperature. As the water continues to get hotter, it begins to undergo a phase change in which water turns to gas. The water droplets turn into water vapor because the temperature has caused the individual water molecules to speed up considerably. This process

    • Law of Universal Gravitation

      Law of Universal Gravitation

      The law of universal gravitation gives the attraction force between two objects due to gravity. Definition: For any pair of objects, they attract each other with a force that is directly proportional to the product of the masses of the objects and inversely proportional to the square of the distance between their centers of mass.

    • Potassium Chlorate

      Potassium Chlorate

      Potassium chlorate is a chemical compound that contains chlorine, oxygen, and potassium. In its pure form, it is white and crystalline in appearance. It is the most common chlorate used in industry, school, research, and commercial labs. Potassium chlorate is commonly used: to prepare oxygen, in safety matches, as an oxidizing agent, in fireworks and

    • Air Exchangers

      Air Exchangers

      An air exchanger is a device that transfers stale air from inside a home to outside, and fresh air from outside to the inside. Air exchangers are often large and built directly into a home’s foundation in order to provide maximum fresh air levels at all times. This is important because indoor air is often

    • Potassium Benzoate

      Potassium Benzoate

      Potassium benzoate is the potassium salt of benzoic acid. Benzoic acids are weak acids that are used as food preservatives. Potassium benzoate is also commonly used for preserving food. It is primarily used to inhibit mold and bacteria growth. This allows the product that potassium benzoate preserves to last longer on the shelf, thereby increasing

    • Electroluminescent Wire

      Electroluminescent Wire

      Electroluminescent wire (EL wire) is a thin wire that produces 360 degrees of visible light. EL wire differs from string lights, such as Christmas lights, which only produce light at specific points. It uses a phenomenon known as electroluminescence to generate light when electricity runs through it. EL wire is very thin and flexible and

      How Does the Biuret Test Work?

      The biuret test is one in which a researcher can determine whether a mixture has peptide bonds in it or not. By using the biuret test, in seconds an individual knows if they are there. Once they know that the peptide bonds are, in fact, there, they can then attempt to measure the amount of

      How Traffic Lights Work

      Traffic lights are basically signalling lights placed at crossroads or turning-points to regulate the flow of vehicular traffic. This system is of utmost importance specially in populated traffic zones to avoid accidents and human casualties. That is most cities deploy traffic signals on every road. Less traffic oriented areas in villages and country side may
