Every kind of technology makes use of principles articulated by the scientific discipline of physics. Even very simple technology, such as the wheel or the lever, have actions that can be described in terms of basic forces and matter interactions.Continue Reading
More complex technology, naturally, makes use of more rarefied physical concepts. GPS satellites, for example, adjust their internal timekeeping to account for the relativistic effects of their motion. Einstein's theory of Special Relativity describes the dilation of time that fast-moving objects experience. Without taking steps to correct for this change in the rate that time passes, GPS coordinates would be inaccurate by an unacceptable factor.
In general, physics describes the sort of things that are possible in the universe, and technology is eventually built to do work within the confines physics has discovered. This interplay works in reverse, as well. While early physicists may have been able to articulate basic principles with little more than thought experiments, modern physicists frequently make use of extremely high-tech machines and processes. The Large Hadron Collider in Switzerland, for example, is the world's largest particle accelerator. It operates at higher energies than any previous collider, and it was built explicitly for the purpose of conducting experiments in particle physics.Learn more about Electricity
Note taking is of the utmost importance for students taking physics classes. While the notes certainly prove to be a helpful resource in and of themselves, the actual process of engaging with the material being taught in a class through the process of taking notes is incredibly formative and helpful for students.Full Answer >
A generator works by converting mechanical energy supplied by an engine into electrical energy, using the principles of Faraday's law of magnetic induction. Magnetic induction is caused by moving a magnet near a conductor, such as coils of copper wire. This movement of the magnet creates an electrical current by inducing a voltage difference, which acts as pressure on the electrons and drives them to flow through a circuit.Full Answer >
The terms watts and ohms refer to different electrical principles, so there is no direct way to convert between them. A watt is a measure of power, and an ohm is a measure of resistance. A voltage source produces power, while a given load absorbs it.Full Answer >
Electric horns use the principles of electromagnetism to operate. A typical vehicle horn system comes with a steel diaphragm, a contractor and an electromagnet.Full Answer >
