Investigatory Projects in Physics | Repulsorlifts as a Method of Stable Magnetic Levitation | Repulsorlifts were used in the study to find out if they can be used to replace the wheels of a conventional car. It was hypothesized that it will be able to lift a car using magnetic repulsion forces. The different magnets were tested individually with the usual tests for magnetic strength‚ size‚ and temperature increase‚ which were done in the preliminary testing. The prototype road and car were

Week #7 Chapter 10 Static and Current Electricity Exercises (p.221) 6. Strictly speaking‚ will a penny be slightly more massive if it has a negative charge or a positive charge? Explain. A negative charge because when it is negatively charged electrons are added to the penny. 17. What is the voltage at the location of a 0.0001 C charge that has an electric potential energy of 0.5 J (both voltage and potential relative to the same reference point)? Potential = energy Charge = 0.5 J / 0.0001

Voltmeter A voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage of the circuit; digital voltmeters give a numerical display of voltage by use of an analog to digital converter. The first digital voltmeter was invented and produced by Andrew Kay of Non-Linear Systems (and later founder of Kaypro) in 1954. RHEOSTAT A rheostat is a device which is used

There are many functions of roller coasters such as the chain lift‚ catapult-launch lift etc. The first component is the chain lift the chain lift is a series of connected carts that move on tracks. The train has no engine nor power source the power is gravity and momentum. To build up this momentum(potential energy) the train needs to get to the top of the hill. The lifting mechanism is a long length of chain that runs up the hill under the track. The chain is a fasten loop and the chain on the

Universe and Inverse are closely related‚ for the effects of known forces of universe are inverse in nature. Ever since Newton made a bold proposition that there is a force of attraction amongst the planets of planetary system‚ amongst different planetary systems and amongst the different galaxies and varies as Inverse Square of their distances‚ people began to correlate every activities of nature and predict its effect accurately. 1.

In 1779‚ he published an important investigation of the laws of friction. In 1785‚ Coulomb presented his three reports on Electricity and Magnetism‚ In these reports he described how to construct and use an electric balance‚ determination of how magnetic and the electric fluids act‚ and the quantity of Electricity. He used the scientific method to observe and testing these experiments repeatedly. He concluded that the electrical force was in some ways very similar to the gravitational force that
