There are two major divisions of physics: classical and modern. Within classical physics, the major subdivisions are mechanics, thermodynamics, acoustics, optics, electricity and magnetism. The subdivisions of modern physics consist of chaos theory, relativity, string theory, cryogenics, crystallography and nanotechnology. The field also includes quantum-level, atomic, molecular, chemical, computational, high-energy, high-pressure and laser physics.Continue Reading
Classical physics is often described as the study of physics on the macroscopic level, meaning questions are generally investigated without the aid of highly technological equipment, such as electron microscopes. The inception of classical physics dates back to the late 1500s. Mechanics is the oldest subdivision of classical physics. The field is inspired by the work of Isaac Newton.
The study of modern physics takes place at the sub-microscopic level. This division of physics investigates the behavior of very small particles, such as electrons and atoms. Modern physics developed in the early 1900s when physicists began to realize that the laws of classical physics did not always hold true for sub-microscopic particles. Notable advances in modern physics include Einstein's theories of relativity and Heisenberg's principle of indeterminacy. Because even the world's most advanced microscopes cannot make sub-microscopic particles visible, expensive tools and equipment, such as particle accelerators, are required to explore the world at this level.Learn more about Physics
Key facts about Albert Einstein for kids include the scientist's status as one of history's most brilliant minds, his development of new ideas in the field of physics and his varied hobbies. Einstein created the famous equation that states that energy equals mass multiplied by the speed of light squared.Full Answer >
The main branches of physics are astrophysics, classical mechanics, electromagnetism, optics, quantum mechanics, relativity and thermodynamics. Physics is the branch of science concerning the study of the nature and properties of matter and energy, and the relationship between them.Full Answer >
The component method is a means of adding different vectors to one another in physics. It enables the addition of right-angled vector components to find a resultant vector having a magnitude and direction that depends on the individual components added.Full Answer >
Some potential investigatory projects that are related to physics include investigating whether repulsorlifts can be used as a method of stable, magnetic levitation, constructing a free-fall apparatus in the absence of equipment, the use of para-toluenesulfonate-doped polypyrolle as an EMF electrode source, and using elastomeric grating for wavelength switching. These are projects or experiments that have been previously carried out and may be repeated to compare results.Full Answer >
