Application of Newton's Laws of Motion
Prima Legge: Particelle in Equilibrio Unidimensionale
Newton's first law of motion states that a body at rest remains at rest, or if in motion, remains in motion at constant velocity, unless acted on by a ...
Prima Legge: Particelle in Equilibrio Bidimensionale
Recall that a particle in equilibrium is one for which the external forces are balanced. Static equilibrium involves objects at rest, and dynamic ...
Seconda Legge: Mozione con la stessa forza
Newton's laws can be applied to bodies at rest and bodies in motion. Newton's first law is applied to bodies in equilibrium, whereas the second ...
Seconda Legge: Mozione sotto la stessa accelerazione
Newton's second law of motion applies to bodies moving under the same acceleration. For example, when a baggage tractor pulls luggage carts, each cart ...
Forza di attrito
When a body is in motion, it encounters resistance because the body interacts with its surroundings. This resistance is known as friction, a common yet ...
Forza di attrito statica e cinetica
One of the simpler characteristics of sliding friction is that it is parallel to the contact surfaces between systems, and is always in a direction that ...
Dinamica del moto circolare
An object undergoing circular motion, like a race car, is accelerating because it is changing the direction of its velocity. This centrally directed ...
Dinamica Del Moto Circolare: Applicazioni
Suppose a car moves on flat ground and turns to the left. The centripetal force causing the car to turn in a circular path is due to friction between the ...
Forza di trascinamento e velocità terminale
An interesting force in everyday life is the force of drag on an object when it is moving in a fluid. Like friction, the drag force always opposes the ...
Tensione
Tension is a force along the length of a medium, in particular, a force carried by a flexible medium, such as a rope or cable. The word "tension" ...
