PIANO INCLINATO

Descrizione:

Per Inclinato si intende una superficie sollevata ad una estremità .Maggiore è l'inclinazione,piú è la velocità dell'oggetto;l'accelerazione con cui un corpo discende un piano inclinato(la cui direzione è parallela alla superficie del piano inclinato)è proporzionale al seno dell' angolo di inclinazione,essendo dovuta alla componente del peso parallela al piano stesso:

a=gsinθ

Detto v il valore della velocità della sfera(oggetto) lungo il piano inclinato,la velocità parallela al piano orizzontale sarà data da:

vcosθ

Quando non c'è frizione,ci sono almeno due forze che agiscono sull'oggetto posizionato:-la forza di gravità e la forza vincolare(perpendicolare alla superficie)

Introduction:

An inclinated plane,also known as a ramp,is a flat supporting surface tilted at an angle,with one end higher then the other. An object on a tilted surface will often slide down the surface.The rate at with the object slides down the surface is dependent upon how tilted the surface is;the greater the tilt of the surface,the faster the rate at which the object will slide down it.

Description:

An inclinated plane is a simple machine with no moving parts.It is a simply an even sloping surface. Inclinated means a rised end or rised at one end.

An inclinated plane has a horizontal side(A),(the distance from the lower end of the slope to the base of the vertical).It also has a vertical side(B),(from the base up to the top of the sloped surface).

An object placed on a tilted surface will often slide down the surface. The rate at which the object slides down the surface is dependent upon how tilted the surface is;the greater the tilt of the surface,the faster the rate at which the object will slide down it.In physics,a tilted surface is called an inclinated plane. Objects are known to accelerate down inclinated planes because of unbalanced force.To understand this type of motion,it is important to analyse the forces acting upon an object on an inclinated plane. Assumed to be friction-free there are always at least two forces acting:-the force of gravity(also known as weight)and the normal force that acts in a direction perpendicular to the surface.
