      What Causes Lightning?

      Lightning can be described as a massive discharge of electrical energy that can reach the speed of 130,000 mph and can exceed temperatures of 30,000 degrees Celsius. Although we know a lot about this phenomenon, it is still unclear how and why lightning forms. We will mention some of the theories on how lightning is

    • How Wind Turbines Work

      How Wind Turbines Work

      How a wind turbine works depends on the type of wind turbine discussed. While most people think of windmills as being the only true type of wind turbine, this is simply not the case, as there are horizontal axis, vertical axis, and various other types of "special" wind turbines in service around the world. Horizontal

    • What Are the Five States of Matter?

      What Are the Five States of Matter?

      There are five states of matter that occur when physical forces are applied to them. These states are fairly easy to understand when their physical properties are observed. Depending on the type of matter that is being dealt with, the state of the matter may be more difficult to reach when applying these physical stressors. The best way

    • Examples of Kinetic Energy

      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

    • The Kelvin Scale

      The Kelvin Scale

      The Kelvin Scale is a thermometric scale used in physical science to describe the absolute temperature of an object, substance, or area. While Fahrenheit and Celsius scales measure temperature, the Kelvin Scale defines temperatures relative to an object’s thermodynamic movement. As a result, the Kelvin Scale does not use degrees, but simply a number followed

    • Vehicle Platooning

      Vehicle Platooning

      Vehicle platooning is one of the innovations in the automotive industry that aim to improve the safety, efficiency, mileage, and time of travel of vehicles while relieving traffic congestion, decreasing pollution and reducing stress for passengers. One of the recent demonstrations of this technology was during the PATH program done in California by 8 Buicks

    • How a Laser Cutter Works

      How a Laser Cutter Works

      A Laser cutter is a machine that uses a laser to cut materials. The Laser Cutter works by making the laser enter through the side of the material that needs to be cut and shoots it through the axis of the beam. If a cut needs to be made and there are no edges near

    • What Causes Radioactivity?

      What Causes Radioactivity?

      Radioactivity is caused when an atom, for whatever reason, wants to give away some of its energy. It does this because it wants to shift from an unstable configuration to a more stable configuration. The energy that is released when the atom makes this shift is known as radioactivity. In other words, radioactivity is the

    • Total Harmonic Distortion

      Total Harmonic Distortion

      Total Harmonic Distortion (THD) is a measured difference in audio levels between the input audio signal’s harmonics and the harmonics of the output audio signal of an amplifier or other audio device. Output Distortion Level As the signal passes through an amplifier it is always somewhat distorted at its output. The waveform at the input

      Combustible Gas Detectors

      A combustible gas detector is a device that allows the user to detect and analyze any nearby concentrations of combustible gases. Combustible gases are simply gases that will catch on fire when mixed with oxygen and ignited. There are many different types of combustible gases and each one requires its own method of analysis. Some
