Coupled pendula

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 ...

Generation of électric currentby means of à pelton turbine

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 ...

Weight

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 ...

Flexion d'une lame-ressort

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 Décomposition des forces sur un plan incliné

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

Oscillation d'un ressort à boudin

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 Le pendule composé

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 ...

Mouvements rectilignes unipourmes avec 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 Lois régissant le mouvement d'accélération unipourme

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 La chute 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 ...

La chute libre avec 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 Quantité de mouvement

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 unipourm motionavec demonstration track and 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.

Accélération due à la pesanteur

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 ...
