There are a large number of sub-branches of physics, but examples include astrophysics, biophysics, electronics, high energy physics and molecular physics. Most scientists become experts in one particular branch, as there is too much knowledge and information in physics as a whole for one person to study it all.Continue Reading
Particle physics is the study of the very small particles that make up atoms. This branch of physics is closely linked with high energy physics, as small particles can often only be studied by colliding particles at high velocities.
Relativity is a branch of physics that was originally developed by Albert Einstein. In this branch, high speed objects are studied to determine how the universe behaves when moving near the speed of light.
There are a number of branches that are exclusively about studying space. Astronomy, for example, is the general study of the universe and the objects within it. Astrophysics is closely related, but is the study of how the physical properties of materials vary throughout the universe.
Cosmology focuses on how the universe began, and how it has changed as a whole. There are a variety of other branches of physics. Examples include computational physics, fluid dynamics and atomic physics.Learn more about Physics
Examples of student physics projects include levitating magnets, building roller coasters, making cars out of mousetraps, designing electric boats, designing bridges and building catapults. To complete the levitating magnets project, a student needs two bar magnets, a flat surface and a notebook.Full Answer >
Some examples of MCAT physics equations include the equation for law of gravitation, which is F = Gm1m2/r^2; the equation for centripetal force, which is F=mv^2/r; and the equations for potential energy, such as PE = mgh, PE = 1/2kx^2 and PE = -GmM/r. Other equations include momentum = mv, impulse = Ft and KE = (1/2)mv^2.Full Answer >
One of the most common definitions for efficiency in physics is a measurement of how much of the desired work or product is obtained from each unit of energy invested into that task or product. An additional definition of efficiency is based on the total amount of energy required to produce a specific amount of a product. Both definitions fall under the category of first law efficiency because they are derived from the first law of thermodynamics.Full Answer >
The work of Sir Isaac Newton revolutionized science and laid the foundations of modern mathematics and physics. Among his accomplishments are the formulation of the laws of motion and gravitation, the development of calculus and the invention of the first reflecting telescope.Full Answer >
