Aplicación de la leyes del movimiento de Newton
Primera ley: partículas en equilibrio unidimensional
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 ...
Primera ley: partículas en equilibrio bidimensional
Recall that a particle in equilibrium is one for which the external forces are balanced. Static equilibrium involves objects at rest, and dynamic ...
Segunda ley: movimientos bajo la misma fuerza
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 ...
Segunda ley: movimientos bajo la misma aceleración
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 ...
Fuerza de fricción
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 ...
Fuerza de fricción estática y cinética
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 ...
Dinámicas del movimiento circular
An object undergoing circular motion, like a race car, is accelerating because it is changing the direction of its velocity. This centrally directed ...
Dinámicas del movimiento circular: aplicaciones
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 ...
Fuerza de arrastre y velocidad del terminal
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 ...
Tensión
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" ...
