    • How Does a Segway Work?

      How Does a Segway Work?

      A Segway is a vertical, mobile vehicle that is able to carry a single person between distances. While a bicycle consists of two wheels and a horizontal frame, a Segway consists of two or four wheels and a vertical frame that balances atop these wheels to steady the rider. Segways run on purely electrical energy

    • What is a Polyolefin?

      What is a Polyolefin?

      One of the largest classes of organic thermoplastic polymers is polyolefin. Polyolefin is an odorless, non-polar, and non-porous material that is used in structural plastics, consumer goods, industrial products, and food packaging. Polyolefin means “oil like” and is commonly referred to as a thermoplastic or polyalkene since polyolefin has a waxy texture. This substance is

    • 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.

    • Who Discovered Quantum and Particle Physics?

      Who Discovered Quantum and Particle Physics?

      During the nineteenth century the main theory in physics was still Newtonian Mechanics. With the advances in electricity, magnetism and the studies about light, it was clear that the theory had its limitations. The limitations appeared in the limits of the too small (atomic size) or the too fast (light speed). The study of the

    • How Do Rockets Work?

      How Do Rockets Work?

      Since the United States first landed a man on the moon, children and adults have been fascinated with how rockets work! Whether one is trying to fly a small model rocket or launching a star ship to rendezvous with the International Space Station, the principles of how rockets work remain the same. Although rocketry has

    • Plasma Gasification

      Plasma Gasification

      Plasma gasification is a new garbage disposal solution using plasma technology. This garbage disposal process is self-sustaining and converts garbage into electricity. Although plasma technology has been around for years, its application to garbage disposal was never seriously considered because the conventional approach of using landfills was less expensive (even with tipping fees and transportation

    • 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

    • 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

    • 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

    • Vibration Isolators

      Vibration Isolators

      There are a number of vibration sources throughout the world. In most cases, these movements have undesirable effects on things used in daily life, such as buildings and vehicles. Vibration isolators reduce or eliminate the effects of vibrations on equipment and structures. These devices are commonly referred to as shock mounts, snubbers, machine mounts, and
