The SI unit of force is the newton (symbol N), which is the force required to accelerate a one kilogram mass at a rate of one meter per second squared, or kg·m·s −2.The corresponding CGS unit is the dyne, the force required to accelerate a one gram mass by one centimeter per second squared, or g·cm·s −2. A newton is thus equal to ...
psychophysics, the science of physical relations in psychology; quantum computing, the study of quantum-mechanical computation systems; sociophysics or social physics, is a field of science which uses mathematical tools inspired by physics to understand the behaviour of human crowds
The following list shows different orders of magnitude of force. Since weight under gravity is a force, several of these examples refer to the weight of various objects. Unless otherwise stated, these are weights under average Earth gravity at sea level.
A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of newtons and represented by the symbol F.
The following index is provided as an overview of and topical guide to science: Links to articles and redirects to sections of articles which provide information on each topic are listed with a short description of the topic. When there is more than one article with information on a topic, the most relevant is usually listed, and it may be ...
1. An applied force or system of forces that tends to strain or deform a physical body. 2. A measure of the internal forces acting within a deformable body. 3. A quantitative measure of the average force per unit area of a surface within a body on which internal forces act. stress–strain curve string duality string theory structural load
force: newton (N) Faraday constant: coulombs per mole (C⋅mol −1) frequency: hertz (Hz) function: friction: newton (N) electrical conductance: siemens (S) universal gravitational constant: newton meter squared per kilogram squared (N⋅m 2 /kg 2) shear modulus: pascal (Pa) or newton per square meter (N/m 2)
Physics – branch of science that studies matter [9] and its motion through space and time, along with related concepts such as energy and force. [10] Physics is one of the " fundamental sciences " because the other natural sciences (like biology, geology etc.) deal with systems that seem to obey the laws of physics.
