The absorbance is the logarithm with a negative sign of the quotient between the emergent light intensity and the incident light intensity on a sample...
The Pascal's barrel It was an experiment carried out by the French scientist Blaise Pascal in 1646 to show definitively that the pressure of a liquid ...
The trajectory in physics It is the curve that a mobile describes as it passes through successive points during its movement. Since it can adopt an in...
The rectilineal movement is the one in which the mobile moves along a straight line and therefore runs in one dimension, hence it is also called one-d...
The Thévenin's theorem states that a circuit with terminals A and B can be replaced by an equivalent one consisting of a source and a series resistanc...
It is understood by director vector one that defines the direction of a line, either in the plane or in space. Therefore, a vector parallel to the lin...
The normal vector is the one that defines the direction perpendicular to some geometric entity under consideration, which can be by a curve, a plane o...
The horizontal shot It is the launch of a projectile with horizontal speed from a certain height and left to the action of gravity. Without taking int...
The oblique parabolic shot is a particular case of free fall motion in which the initial velocity of the projectile forms a certain angle with the hor...
