Weight with measureAPP



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 measured ...

Bending of a leaf spring with measureAPP

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original shape is re-formed when the force is no longer active.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

Reversible pendulum (physical pendulum)

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 reversion pendulum: there ...

Uniform linear motion with thetimer 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.

From the ...

Uniform linear motion with Cobra4

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.

From the measurement values ...

Comparison of uniform and non-uniform motion with the 2-1

Principle

In this experiment the pupils should see that motions are typically not uniform. This should increase their understanding of the concept of instantaneous speed.

Benefits

• Especially accurate and reproducible results due to the use of light barriers and the ...

Comparison of uniform and non-uniform motion with Cobra4

Principle

In this experiment the pupils should see that motions are typically not uniform. This should increase their understanding of the concept of instantaneous speed.

Benefits

• Entrance to the world of datalogging by using the Cobra4 Mobile-Link
• The use of the compact Cobra4 ...

Instantaneous and average speed with the 2-1 timer

Principle

In this experiment, the pupils should observe quantitatively those differences between uniform and non-uniform motion and they should become familiar with the concept of instantaneous speed. This clarifies the average speed which is contrasted with the instantaneous ...

Laws of uniform linear motion with the 2-1 timer

Principle

In this experiment, pupils should determine the laws of motion associated with uniform straight motion. Particularly, the presentation of the course of motion should be prepared in a distance-time graph and a speed-time graph.

Benefits

• Especially accurate and ...

Laws of uniformly acceleration motion with the 2-1 timer

Principle

In this experiment, pupils will examine acceleration in an example of motion under constant acceleration, and they will sum up the laws of motion in the form of graphs. By comparing slopes contained in the s/t² and the v/t graphs, the proportionality factor k in the ...
