Basic Math for Physics" Tutorial Summary Mathematics is vital to your study of physics. Algebra is needed to isolate and solve for whatever variable is desired.

Vector, in physics, a quantity that has both magnitude and direction. ... For example, displacement, velocity, and acceleration are vector quantities, while speed (the magnitude of velocity), time, and mass are scalars.

The Root of All Calculus. Calculus or mathematical analysis is built up from 2 basic ingredients: integration and differentiation. Differentiation is concerned with things like speeds and accelerations, slopes and curves etc. These are Rates of Change, they are things that are defined locally.

Calculus – differentiation, integration etc. – is easier than you think. Here's a simple example: the bucket at right integrates the flow from the tap over time. The flow is the time derivative of the water in the bucket. ... Calculus analyses things that change, and physics is much concerned with changes.

Kinematics, branch of physics and a subdivision of classical mechanics concerned with the geometrically possible motion of a body or system of bodies without consideration of the forces involved (i.e., causes and effects of the motions).

Newton worked in many areas of mathematics and physics. ... Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia.

Work, Power and Energy. When a force acts on an object and the object actually moves in the direction of force, then the work is said to be done by the force. ... Work is a scalar quantity, Its S1 unit is joule and CGS unit is erg.

Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.

Under certain circumstances the linear momentum of a system is conserved. The linear momentum of a particle is related to the net force acting on that object: ... " The linear momentum of a system of particles is equal to the product of the total mass M of the system and the velocity of the center of mass

This force changes the motion of objects. ... Thus, the torque is a force which is studied under rotational dynamic. In rotational motion, the object is not treated as a particle but is treated in translational motion. The rotational dynamics starts with the study of Torque that causes angular accelerations of objects.

In physics, a fluid is a substance that continually deforms (flows) under an applied shear stress. Fluids are a subset of the phases of matter and include liquids, gases, plasmas, and to some extent, plastic solids. ... The distinction is made by evaluating the viscosity of the substance. The cohesive forces among liquid molecules are responsible for the phenomenon of surface tension. In the bulk of the liquid, each molecule is pulled equally in every direction by neighboring liquid molecules, resulting in a net force of zero.

Heat is a form of energy that can be transferred from one object to another or even created at the expense of the loss of other forms of energy. To review, temperature is a measure of the ability of a substance, or more generally of any physical system, to transfer heat energy to another physical system. Thermodynamics is the branch of physics that deals with the relationships between heat and other forms of energy. ... Thermal energy is the energy a substance or system has due to its temperature, i.e., the energy of moving or vibrating molecules, according to the Energy Education website of the Texas Education Agency.

In mechanics and physics, simple harmonic motion is a special type of periodic motion or oscillation motion where the restoring force is directly proportional to the displacement and acts in the direction opposite to that of displacement. In physics, elasticity (from Greek ἐλαστός "ductible") is the ability of a body to resist a distorting influence and to return to its original size and shape when that influence or force is removed. Solid objects will deform when adequate forces are applied on them

In physics, a wave is an oscillation accompanied by a transfer of energy. Frequency refers to the addition of time. Wave motion transfers energy from one point to another, which displace particles of the transmission medium–that is, with little or no associated mass transport

Electrostatics is a branch of physics that deals with study of the electric charges at rest. ... Electrostatic phenomena arise from the forces that electric charges exert on each other. Such forces are described by Coulomb's law.

An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionised gas (plasma). ... These conduction electrons are the charge carriers in metal conductors

Magnetostatics - University Physics Tutorials. Magnetostatics is the study of the Magnetic Field produced by steadily moving electric charges. ... Therefore, the study of Magnetostatics is really about defining a vector magnetic potential 'A' and using this potential in order to evaluate the field and the force it produces

Electromagnetic or magnetic induction is the production of an electromotive force (i.e., voltage) across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction.

Alternating current (AC) is an electric current which periodically reverses direction, in contrast to direct current (DC) which flows only in one direction. ... The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage.

Geometrical optics, or ray optics, describes light propagation in terms of rays. The ray in geometric optics is an abstraction useful for approximating the paths along which light propagates under certain circumstances. ... propagate in straight-line paths as they travel in a homogeneous medium.

In physics, physical optics, or wave optics, is the branch of optics that studies interference, diffraction, polarization, and other phenomena for which the ray approximation of geometric optics is not valid.

Modern physics is the post-Newtonian conception of physics. It implies that classical descriptions of phenomena are lacking, and that an accurate, "modern", description of nature requires theories to incorporate elements of quantum mechanics or Einsteinian relativity, or both.
