Elasticity and Fracture
When an object is at rest, we can think that it is not interesting to study because it does not have speed or acceleration and because the forces which are acting on it are zero. […]
Force and Pressure in Fluids
The three common states, or phases, of matter, are solid, liquid, and gaseous. The solid maintains a fixed shape and size; even when a large force is applied, a solid will not change easily in […]
Collisions
When two or more bodies approach each other, internal forces act between them, causing a variation in their linear momentum and in their energy, producing an exchange between them of both magnitudes. In this case, […]
The circular movement
The circular movement, also called, of curvilinear trajectory is much more abundant than the rectilinear movement. These are based on an axis of rotation and constant radius, whereby the trajectory is a circumference. Uniform Circular […]
The rectilinear movement
Movement is one of the physical phenomena that we most directly perceive, but the form of that movement depends on the place from which it is observed. It is the so-called “reference system (SR)”. […]
Gravitational Field, Electric Field and Magnetic Field
Comparative study between the Gravitational Field, Electric Field and Magnetic Field GRAVITATIONAL FIELD ELECTRIC FIELD MAGNETIC FIELD Source Body mass (punctual or mass distribution) Electric charge (punctual or mass distribution) Magnetic field […]
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 […]
