Péndulos acoplados en tablero magnético con 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 coupled ones. Only so can waves ...

Péndulos acoplados con Cobra4 (con material de soporte)

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 coupled ones. Only so can waves ...

Calidad del auga - contaminación con metales pesados

Principle

Heavy-metal ions may be carried into surface or ground water from mining fields or via the waste water of galvanicor similar production sites. They block the effect of enzymes so that the processes in the metabolism of the organisms that are controlled by these enzymes may be ...

Calidad del auga - contaminación con metales pesados con Display Connect

Principle

Demonstration experiment using wireless data transmission to a large digital to display. Heavy metal ions can seep into water courses, for example from galvanising plants or other similar industries. They have the effect of suppressing the action of enzymes, so that the ...

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 be ...

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original shape is re-formed when the force is no longer active. ...

Fricción con Cobra4

Principle

We deal with friction in our everyday lives and in technology. Without exception every movement on Earth is connected to friction, and therefore with a loss of energy and wear. Without friction, however, movement would not be possible at all. You could not walk, stop, hold on to ...

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 rest position with an oscillation period ...

Equilibrio térmico con Cobra4

Principle

Why do tea or coffee get cold onstanding, but never hot?

Tasks

Watch the water temperatures when a vessel containing cold water is dipped into a hot water bath.

Aislamiento térmico con Cobra4

Principle

A quick loss of heat is sometimes not wanted. What can be done to keep the temperature in a vessel
constant?

Tasks

Measure the cooling of hot water in two different environments:

  • In a glass beaker that is fitted out with thermal insulation in the form of felt sheets ...

Calentamiendo del agua con Cobra4

Principle

How depends the time required to heat up water on the amount of water when a defined heating source is available?

Tasks

Heat up various amounts of water with an electric heating coil and measure the time dependence of the
temperature increase.

Calentamiento de diferentes líquidos con Cobra4

Principle

Do different liquids heat up to the same extent when subject to the same heating?

Tasks

Heat 100 g and 100 ml of water and of glycerol with an electric heating coil and measure the temperature
in dependence on time.

Capacidad calorífica específica del agua con Cobra4

Principle

In households, a great amount of energy is used to heat up water - for showers, for washing clothes, for cooking. Exactly how much is necessary for each degree that each mililitre of water is warmed up? How are amount of heat, heat capacity and change in ...

Calor de mezclas y capacidad calorífica de un calorímetro con Cobra4

Principle

Quantities of heat distribute themselves so that finally all parts that are in contact with each other have the same temperature. If the heat capacities and the initial temperatures are known, then the final temperature can be predicted. Or, in reverse, the final temperature can ...

Capacidad calorífica de metales con Cobra4

Principle

The calorimeter can be used to determinethe heat content of a piece of metal.The heat content can be calculated fromthe mixing temperature that is reachedin the calorimeter.

Tasks

Heat up metal bodies of the same mass but different metals to the same temperature in a water ...
