### Capacitance theory

Capacitance   Capacitance is the ability of a body to store charge in an electric field. Capacitance is also a measure of the amount of electric potential energy stored (or separated) for a given electric […]

### Direct-Current theory

Direct-Current   When it is connected a continuous conductive path, like a wire with a battery terminal, we obtain an electric circuit. The device which receives charging from a battery is not always a wire, […]

### Rotation theory

Rotation   A Rotation is a circular movement of an object around a center (or point) of rotation. A three-dimensional object rotates always around an imaginary line called a rotation axis. A rotation of a […]

### Oscillations theory

Oscillations   Oscillations are the repetitive variation, disturbance or fluctuation over the time measure about a central value or system. A particle oscillates periodically when it moves relative to its equilibrium position. Simple harmonic motion […]

### Statics theory

Statics   Statics is the branch of mechanics that studies the bodies in condition of balance submitted to the action of forces. Strength is the action that one has on something, either by pulling or […]

### Dynamics theory

Dynamics   Dynamics is the part of physics that describes the time evolution of a physical system in relation to the causes of changes in physical and/or movement state. Dynamics’ aim is to describe factors […]

### Kinematics theory

Kinematics   Kinematics is the branch of classical mechanics that describes the motion of bodies (objects) and systems (groups of objects) without consideration of the forces that cause the motion. When we study the motion […]

### Second Principle of Thermodynamics theory

Second Principle of Thermodynamics   Thermodynamics is the branch of physical science concerned with heat and its relation to other forms of energy and work.   It defines macroscopic variables (such as temperature, entropy, and […]

### First Principle of Thermodynamics theory

First Principle of Thermodynamics   Thermodynamics is the branch of physical science concerned with heat and its relation to other forms of energy and work; it is studied in processes in which there is transfer […]

### What is an Electric Field

Electric Field theory   The Electric Field is the region of space in which any cargo located at a point in that region undergoes an action or electrical force due to the presence of a […]
