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 ...
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 A characteristic of such an elastic deformation is that the original shape is re-formed when the force is no longer active.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 ...
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 ...
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 ...
From the measurement values ...
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
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 ...
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.
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 ...
