In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field. Physics is derived of formulae only.
Until 2012, the All India Pre-Medical Test (AIPMT) was conducted by the Central Board of Secondary Education (CBSE). In 2013, NEET-UG was introduced, conducted by CBSE, replacing AIPMT. However, due to legal challenges, NEET was temporarily replaced by AIPMT in both 2014 and 2015. In 2016, NEET was reintroduced and conducted by CBSE.
The following is a list of notable unsolved problems grouped into broad areas of physics. [1]Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result.
A set of equations describing the trajectories of objects subject to a constant gravitational force under normal Earth-bound conditions.Assuming constant acceleration g due to Earth's gravity, Newton's law of universal gravitation simplifies to F = mg, where F is the force exerted on a mass m by the Earth's gravitational field of strength g.
Physics is the scientific study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. [1] Physics is one of the most fundamental scientific disciplines. [2] [3] [4] A scientist who specializes in the field of physics is called a physicist.
University Physics, informally known as the Sears & Zemansky, is the name of a two-volume physics textbook written by Hugh Young and Roger Freedman. The first edition of University Physics was published by Mark Zemansky and Francis Sears in 1949. [2] [3] Hugh Young became a coauthor with Sears and Zemansky in 1973.
The same physical constant may move from one category to another as the understanding of its role deepens; this has notably happened to the speed of light, which was a class A constant (characteristic of light) when it was first measured, but became a class B constant (characteristic of electromagnetic phenomena) with the development of ...
Fear of Physics: A Guide for the Perplexed is the second non-fiction book by the American physicist Lawrence M. Krauss. [1] It was published in 1994 by Basic Books . The book contains many anecdotes and examples.
