Fuerzas y recorridos en polea loca

Principle

  1. The students should determine the forces which occur on both supporting lines of a movable pulley when it is loaded with various masses.
  2. Further, they should change the point of impact of the force (the force distance) and examine the effect on the load (load distance). ...

Polipasto con una polea loca y una fija

Principle

The students should recognize on a simple block and tackle that the force required to lift a specific load can be reduced by half compared with the weight (force) by using an arrangement of 2 pulleys. However, a longer distance must be covered. By comparing the products ...

Polipasto de 4 poleas

Principle

Using a block and tackle as an example, the students should observe that the force, which is necessary to lift a given load, decreases in direct correlation with the number of pulleys.

  1. They should determine how much larger the weight force of the load is compared ...

Fuerzas y recorridos en una rueda escalonada

Principle

  1. The students should measure the forces which maintain equilibrium with different load masses on a step wheel.
  2. They should measure the force and the length of the load arms of a step wheel, and calculate the products load × load arm ...

Vasos comunicantes

Principle

Using a flexible U-tube consisting of two glass bells and a piece of tubing, the students should investigate how the water level in the two sides of the U-tube behave when the relative positions of the two tubes are changed.

Benefits

  • Student-suitable experiment descriptions ...

Presión hidrostática

Principle

The students should determine the directional independence of hydrostatic pressure (termed as top, lateral and bottom pressure) with the aid of 3 hydrostatic pressure probes.

Additionally, they should measure the hydrostatic pressure as a function of immersion depth ...

Empuje y flotación

Principle

The students should determine whether or not various objects float in water. They should then investigate whether the volume of an object or its shape affect its buoyancy.

 

Benefits

  • Student-suitable experiment descriptions with reports available

Principio de Arquímedes

Principle

The students should determine the weight (force) of an object in air and then in water. From the difference they should calculate the buoyancy Fb

In a second experiment, the students should determine the mass of the water displaced by the immersed object; from this ...

Determinación de la densidad de sólidos midiendo el empuje

Principle

In this experiment the students should recognize that the density of solid objects can be determined by measuring only the buoyancy. The required computations can be given or worked out by the students on their own, in part as an additional Task.

Benefits

  • Real stand ...
