We propose a new tool for laboratory curricula based on computer-aided data acquisition and analysis. A pendulumcoupled to a low-friction rotary sensor offers variable length, variable mass, variable oscillation plane (to change theeffective gravitational restoring torque) and two different kind of ...
Dynamics of the looping pendulum: theory, simulation, and experiment The looping pendulum is a simple physical system consisting of two masses connected by a string that passes over a rod. We derive equations of motion for t... C Dannheim,L Ignell,B O'Donnell,... - 《European Journal of...
In this experiment a sphere of solid material was moved through a liquid of identical weight density. The absence of a gravitational effect on a nearby Cavendish balance instrument during the sphere’s motion is interpreted as showing that the two materials had equal potency in producing a local...
As is well known, simple pendulums represent widely studied models of nonlinear oscillators, ex- hibiting a variety of physically interesting dynami- cal properties. When coupled in linear chains, for example, they are often used as models for arrays of short Josephson junctions or series of non...
This is partly because the mathematics in this field is highly complicated. At the same time, it is tough to perform suitable experiments: One would have to create situations in which phenomena of both the relativity theory play an important role, for example, a spacetime curved by heavy ...
(t). What is fixed and what is variable is somewhat arbitrary, and the distinction is made for clarity rather than any fundamental reason. In a different version of the experiment, the classification of fixed and control param- eters might differ. In the harmonic-oscillator example, we might...

Trim up to the first notch to speed up the pendulum. For the caterpillar - Cam 3 - Roll = left / right. pitch = look up / down, YAW in case he is on his back (from fighting with amoebae) and AG1 to turn on magnetic feet. He can climb all over and under bridges and such....
12 dence, experiment, modeling, questions of realism, differences between special sciences, and many other separate issues. Most of these relate to explanation in some way, but they are not exhausted by that relation. Inference to the best explanation figures in many debates about realism, for ...
The formal operational stage is the final stage Piaget described. At this stage, children and adolescents can experiment by forming hypotheses and testing them systematically. This way of thinking involves abstract concepts, separating form from content (hence the name “formal operations”), and cons...
