  With this free course of 16 video lessons you will learn about the most important concepts of Linear Momentum in Physics

  The amount of motion, linear momentum, momentum, or momentum is a physical magnitude derived from the vector type that describes the motion of a body in any mechanical theory. In classical mechanics, the amount of motion is defined as the product of the mass of the body and its velocity at a given instant. Historically, the concept dates back to Galileo Galilei. In his work Discourses and mathematical demonstrations around two new sciences, he uses the Italian term impeto, while Isaac Newton in Principia Mathematica uses the Latin term motus1 (movement) and vis motrix (motive force).

• Physics Course - Work and Energy

  With this free course of 20 video lessons you will learn about the most important concepts of Work and Energy in Physics

  In classical mechanics, a force is said to perform a job when there is a displacement of its point of application in the direction of that force. The work of the force on that body will be equivalent to the energy needed to move it. Consequently, a certain mass is said to have energy when that mass has the capacity to produce work; Moreover, it follows from this statement that there is no work without energy. For this reason, it is said that coal, gasoline, electricity, atoms are sources of energy, since they can produce some work or be converted into another type of energy; To understand this, we take into account the universal principle of energy, according to which energy is neither created nor destroyed, it is only transformed.

  With this free course of 53 video lessons you will learn about the most important concepts of Dynamics in Physics

  Dynamics is the branch of physics that describes the evolution over time of a physical system in relation to the motives or causes that cause changes in physical state and/or state of motion. The objective of dynamics is to describe the factors capable of producing alterations in a physical system, to quantify them and to propose equations of motion or equations of evolution for that system of operation. The study of dynamics is prominent in mechanical systems; but also in thermodynamics and electrodynamics. This article describes the main aspects of dynamics in mechanical systems, and reserves for other articles the study of dynamics in non-mechanical systems, work and energy.

  Con este curso gratuito de 22 lecciones en vídeo aprenderás sobre los conceptos más importantes de Movimientos en Física

  En mecánica, el movimiento es un cambio de la posición de un cuerpo a lo largo del tiempo respecto de un sistema de referencia.

  The study of movement can be done through kinematics or through dynamics. Depending on the choice of the reference system, the equations of motion will be defined, equations that will determine the position, speed and acceleration of the body at each instant of time. Every movement can be represented and studied by means of graphs. The most common are those that represent space, velocity or acceleration as a function of time.
