Schlichting, H. Joachim; Wilfried Suhr: The bicycle as a universal means of transportation - a double-wheeled energy safe-box
In: Physik in unserer Zeit 39/2 (2008) 86 - 89

The paper compares the bicycle as a suitable means of transportation in everyday life on the one hand with walking and motorized means of transportation on the other hand. In order to avoid ideological biases, the analysis will be restricted to effectively measurable energetic costs of transportation. This approach also underlines the equivalence of costs and energy, which is a concept students must be aware of in order to fully understand the economic impact of the global energy crisis.

Suhr, Wilfried; Schlichting, H. Joachim: Bicycling - Pedalling against hills and wind
In: Physik in unserer Zeit 38/4 (2007) 294 - 298

Why do the favorites of a cycle race save their attacks against their rivals for the Alpine stages? And why do they fear the wind especially during the individual time trials?  The physical explanations to these questions may be provided by the model of driving resistance presented in this paper.

Suhr, Wilfried; Schlichting, H. Joachim: The physics of bicycling: Equilibrium on two wheels
In: Physik in unserer Zeit 38/5 (2007) 238 - 241

The paper exemplifies general principles of equilibrium by the means of an easily accessible model of the bicycle. Notwithstanding its simplistic appeal, the model facilitates a qualitative understanding of the underlying physical principles.

Schlichting, H. Joachim; Suhr, Wilfried: Modern-day Centaurs [fraglich ob der Link stimmt!?]
In: Physik in unserer Zeit 38/4 (2007) 184 - 188

Why do the favorites of a cycle race save their attacks against their rivals for the Alpine stages? And why do they fear the wind especially during the individual time trials?  The physical explanations may be provided by the model of driving resistance presented in this paper

Schlichting, H. Joachim:  Schleuderball
Naturwissenschaften im Unterricht - Physik 3/12, 18 (1992).

The paper discusses the cognitive problems which may arise from the modern perspective on circular paths as bended straights. It is shown that the majority of problems originates from the learners' intuitive adherence to the Aristotelian concept of a perfect circle. It is argued that the ubiquitousness of the latter in our everyday lives impedes an analytical approach to the principles of circular motion in modern physics.

Schlichting, H. Joachim: Simple topics related to the physics of sports
In: Naturwissenschaft im Unterricht - Physik 3/12, 7 (1992).

This summary of a selection of physical concepts and models, which are important for various sports and the functions of sports equipment and utilities, shall provide teachers with a theoretical foundation for physics lessons on sports. The simple models are intentionally restricted to the qualitative explanation of the underlying phenomena – the additional equations may however be used by the teacher for his/her own numerical estimations.

Schlichting, H. Joachim: The physical dimension of sports
In: Naturwissenschaften im Unterricht - Physik 3/12, 4 -6 (1992).

Next to games and toys, sports seems to be one of the most promising ways to realize and practice the switch from an everyday to an abstract physical perspective. This article discusses the various ties of sports and fundamental physical concepts such as energy, forces, equilibrium etc. An emphasis is on corresponding didactic means, which may foster the students' abilities to recognize the presence and significance of these concepts in and for their everyday lives.

Rodewald, Bernd; Schlichting, H. Joachim: Jumping, Walrking, Running
In: Praxis der Naturwissenschaften - Physik 37/5, 12 (1988).

The paper is concerned with the locomotion of man. Accessible by the means of very simple experiments with one's own body, it is an excellent field of application for the fundamental principles of mechanics and energetics. An initial analysis of jumping as a typical means of locomotion for frog, kangaroo, flea or locust provides the basis for the exploration of more complex processes such as walking and running.

Schlichting, H. Joachim; Rodewald, Bernd: The boomerang - A toy of remarkable flight qualities
In: Praxis der Naturwissenschaften - Physik 35/5, 18 (1986).

A simplified description of the underlying physical principals of the flight of the boomerang is presented. Despite being intended to be used in the German Sekundarstufe (Middle School, Junior High), this elementary model may well be extended into a consecutive quantitative description of this amazing hunting-device.

Schlichting, H. Joachim: Going over the handlebar - On the problem of braking a bicycle
In: technic-didact 10/1, 49 (1985).

The paper outlines the rotation of bicycles around an axis transversally to the direction of motion. This rotation is determined by the different torsional moments of braking. In view of accessibility the discussion of these moments is restricted to qualitative arguments and several quantitative estimations.

Schlichting, H. Joachim: Equilibrial problems of bycicling
In: technic-didact 9/4, 257 (1984).

Due to its high individual variability, the attempt to deliver a complete mathematical description of bicycling seems futile. Accordingly, this article discusses the principal equilibrial mechanism for an average bicycler on a standard bicycle. Additional quantitative estimations facilitate an assessment of the order of magnitude of the corresponding physical quantities.

Schlichting, H. Joachim: Bicycling, walking, driving. An interesting comparison for the physics classroom
In: technic-didact 9/3, 177 (1984).

The paper analyses the energetic costs of transportation of bicycling and compares these to other means of transportation in representative situations. For obvious reasons a comparison like this must remain relatively undifferentiated. Consequently, the paper will focus on walking or running as a natural means of locomotion without technical aids and on driving a car as an example of motorized transportation. The deliberate restriction to the discussion of the energetic costs of transportation is also intended to emphasize the close relationship of energetic and economic costs, the awareness of which is a prerequisite of an adequate understanding of the economic effects of the global energy-crisis.

Schlichting, H. Joachim; Nobbe, Reinhold: Investigations into the energetics of bicycles
In: technic-didact 8/4, 225 (1983).

The paper investigates the influence of drag on bike and bicycler. Based on an analysis of the effects of the wind in selected situations, possible strategies of the bicycler to directly influence the air-resistance are discussed.

Schlichting, H. Joachim; Backhaus, Udo: Everyday physics exemplified by the energetics of bicycles
In: technic-didact 8/1, 27 (1983).

It stands out of question that the students' difficulties with and consequent reluctance of abandoning or modifying their everyday concepts of their physical environment in favor of scientific ones constitute one of the main reasons for the empirically validated unpopularity of physics courses at German schools. To overcome such obstacles and to facilitate learning, it is important to select topics and contexts in which learners may practice the adoption of a physical perspective on otherwise familiar objects. With the analysis of the energetics of bicycles, a viable example will be presented in this paper.
