Péndulos acoplados en el tablero magnético y Cobra4

Principle

Oscillations occur in physics in an extremely wide range of occurrences.They are macroscopically visible in the swinging and cushioning of cars or suspension bridges. In Nature, however, there is as a rule never a single oscillation but always only co ...

GENERACIÓN DE CORRIENTE ELÉCTRICA CON TURBINA DE PELTON

Frequency of waves

Principle

In this experiment a geared motor (30:1 ratio) is used to drive the elastically coupled elements of a wave machine via an eccentric. In order to suppress reflections at the open end of the oscillating system, the small bars under the oscillating pieces are allow ...

Peso con Cobra4

Principle

"A mass is not only inert but also heavy." Which is intended to mean that not only is a force necessary to accelerate a mass, but also that each mass in the earth's gravitional field experiences a force, the force of weight. The force of weight is to ...

Flexión de una lámina elástica con Cobra4

Principle

Leaf springs are thin metal plates that are elastically deformed under load: When a force is applied to a
leaf spring, then it is subject to deformation. A characteristic of such an elastic deformation is that the
original shape is re-for ...

ME 2.9 Descomposición de fuerzas en un plano inclinado

Principle

The students should - experimentally - gain knowledge of the resolution of the weight (force) F_g of a car on an inclined plane into a normal force F_n ,acting perpendicular to the track, and a downhill force

Oscilador de muelle helicoidal con Cobra4

Principle

In this experiment observations are to be made on a spring pendulum which consists of a helical spring
with a spring constant D and a mass m which is hung on it. When the pendulum is displaced by smax and
let go of, it swings across its r ...

ME 5.7 Péndulo reversible (péndulo físico)

Principle

In the "Simple pendulum" experiment (Mechanics 5.2) the students became acquainted with the correlations between pendulum length and oscillation period of a thread pendulum. In the present experiment they should discover the special property of a ...

Movimiento rectilíneo uniforme Timer 2-1

Principle

The pupils should develop the notion of linear uniform motion experimentally, by deriving the speed of the powered car from the measurement of the distance and time. The experiment should be carried out with different distances and car speeds.
...

ME 6.5 Leyes del movimiento uniformemente acelerado

Principle

In this experiment, the students should explore the concept of acceleration by using uniformly accelerated motion as an example, and recognize the laws of the motion with aid of diagrams. By comparing the slopes obtained from s

ME 6.7 Caída libre

Principle

The students should investigate the free fall of an object in the gravitational field of the Earth and record the fall with a recording timer and recording tape. From the data obtained they should determine the acceleration of the falling body, which ...

Caída libre Timer 2-1

Principle

Pupils should examine a body's free fall under the earth's gravitational pull with the timer, a starting apparatus and a photoelectric gate, and they should determine the earth's gravitational acceleration from the information obtained.

ME 6.10 Impulso

Principle

The students use two cars joined under spring pressure to investigate impulse. When the cars are released from each other, they should examine how the impulse is distributed onto each of them and whether the total impulse (zero) is conserved.

Linear uniform motion with the demonstration track and the timer 4-4

Principle

A glider is repeatedly accelerated to a constant velocity by the mechanical starter system. The average velocity and the instantaneous velocity are determined at different distances from the starter system.

LB 2.5

Principle

For determining the gravitational acceleration of the Earth (g) using the familiar distance-time relationship for accelerated movement with a falling sphere apparatus. A steel sphere is held in the release mechanism between a pin and a plunger, thereby closing a ...
