    The project that will be tested is called The Effect of the Ion Engine propulsion system on a Space Shuttle launch. To effectively understand the project background information will be needed. The observers will need to understand the following terms which are: ions, ion engine, conservation of momentum, atoms, ionization and Newton’s law. It is also important to effectively understand why an ion system would be used and why it is the best, as well as being knowledgeable about the different components

    Dielectric Essay

    • 951 Words
    • 2 Pages

    A dielectric material is a substance that is a poor conductor of electricity. If the flow of current between opposite electric charge poles is kept to a minimum while the electrostatic lines of flux are not impeded or interrupted, an electrostatic field can store energy. Most dielectric materials are solid. Examples include porcelain (ceramic), mica, glass, plastics, and the oxides of various metals. Some liquids and gases can serve as good dielectric materials. Dry air is an excellent dielectric

    Within the world, many times we have to reevaluate and consider multiple varying possibilities. Nothing is ever completely known, so when new discoveries are made about a topic that has already been previously discovered we must readapt our way of thinking about something that we believed we had used to know. In order to evaluate the quote, “That which is accepted as knowledge today is sometimes discarded tomorrow,” we must first define key words within the phrase to get a better understanding of

    produced; * In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. Conductor implies that the outer electrons of the atoms are loosely bound and free to move through the material. Most atoms hold on to their electrons tightly and are insulators. It is the ability of these electrons to drift from

    Electrstriction :-It is a second order effect.Whenever on application of an electrical field a change in shape occurs,proportional to the square of that field..This process is irreversible,occurs in all dielectric materials,caused by randomly aligned electrical domains,the applied field aligns electrical domains,opposite of domains attract each other reducing thickness of materials along the direction of electric field.An important point to note is electrostrictive deformations are far much saller

    Resistance of a Wire

    • 1488 Words
    • 3 Pages

    an electrical circuit (the electrical charge), but before the electrons flow through the circuit, a voltage (or potential difference) must be applied. This provides the "pressure" to push the electrons forward. A battery for example would give a potential difference to a circuit and provide the force to begin the flow of electrons through it. Resistance is measured in Ohms (W). It is anything in the circuit that opposes the flow of an electrical charge. Every component in a circuit causes

    together in a regular pattern and electrical forces hold these together. The tight packing causes outer electrons to get separated from their atoms. This is the reason why metals are good conductors of electricity as the electrons are free to carry charge. When a voltage is applied across a wire, the electrons drift through the metal. It is an unsteady motion as the electrons continually collide with the ions. The electrons accelerate, collide with the ions and stop. However, because there is

    The graph on the side illustrates the current through a resistor is proportional to the voltage. V=IR gives the formula for Ohms law. In order for current to flow it requires electrons to carry the electric current. The electrons are the negative charge that can freely move about. Within metals there are a sea of electrons that can carry the electric current, which is reason why they conduct so well and are used for many purposes, such as wires. Factors During the investigation there will be many

    difference (voltage) across it. As the current continues to flow there are certain factors which increase the resistance; Length of wire: as the length increases there will be a higher percentage of fixed atoms, therefore the electrons carrying the charge will collide more frequently, increasing the resistance Surface Area of wire- As you increase the surface area of a wire the resistance will decrease because the electrons will be able to travel by many different routes making the conduction

    The notion of the atom all stared about 450 BC when a Greek scholar starting think when can something break on more, when are the pieces at their smallest, this mans name was Leucippus. Leucippus also had pupil who also thought the same way as Leucippus, his name was Democritus. They developed there ideas and when Democritus died his theory summed up briefly was that everything in the world was made of tiny pieced that could not be broken up any more. That how the word atom was derived from the Greek
