Desplazamiento lineal y desplazamiento angular.
In our surroundings there are not only rectilinear motions, but also objects that rotate, revolve and as the ceiling fan or the container of the washing machine, which describe circular motions.
Analogous to the rectilinear movement, it can be said that the angular displacement of a particle along a circular path is
[pic 1]
Unidades de medición de desplazamiento angular
One of the units that is commonly used to express the angular displacement is the sexagesimal degree (°); and we all know that in a complete circle there are 360[pic 2]
another unit of mea sure of angular displacement. This unit is known as radian. A radian is an angle formed at the center of a circle by a circumference are, whose length is the same as the radius of a circle.
Velocidad lineal y angular
The concept of velocity related to the rectilinear motion, that has be previously described is defined as the ratio of position change with time Analogously, it can be said that, if a particle or an ob moves along a circular path in a time interval At, it defines the rotation ratio, which is called angular velocity, and is represented by the Greek letter omega
In summary, the angular velocity is the magnitude of angular displacemen divided by the time it took the object to travel that angle.
Unidades de velocidad angular
The units of the angular velocity in the international system are expressed in radians per second, but you can also write s¹ since the radian is a dimensionless unit
Frecuencia y período en el movimiento circular
Frequency represents the number of times an event repeats for each unit of time elapsed. For the case of circular motion, the frequency per unit time represents the number of turns or revolutions that an object makes around an axis.
We will now define as the period of time it takes an object in circular motion to make a complete revolution, it is represented by the letter T.
Aceleración centrípeta y fuerza centrípeta
In a circular path, the acceleration points directly toward the center of the circle; This is called centripetal acceleration, which is directed radially towards the center of rotation and is what causes the movement in a circular path and not in a straight way.
Magnitudes lineales y angulares | Semejanzas | Diferencias |
Desplazamiento lineal y Desplazamiento angular | Both linear displacement and angular displacement depend on a linear velocity. In both movements there is a defined and particular trajectory. Both displacements have basic elements such as acceleration force moment and others | Linear displacement represents the distance that the mobile travels on the trajectory, while the angular displacement is the angles swept by the mobile along the trajectory. |
Velocidad lineal y Velocidad angular | In a uniform circular motion that both can be kept constant in the direction and sense module, in addition to that if they varied the mation would become a uniformly varied circular motion | The angular velocity: it is the relation or circular velocity Linear spees the speed in a straight line |
Movimiento rectilíneo y Movimiento circular | Linear speed A displacement is generated in both movements There are acceleration | The circular movement has an angular displacement and the rectlinear one appears linear |
