Method I–Stokes' law uses a term that is proportional to the sphere's speed v; Method II–
Landau–Lifshitz model uses a much more complicated expression for FD than Method I and …

In this study, we manipulated the swimming direction of bacteria and controlled the switching
off movement by using dc and ac galvanotaxis. The microstructures blotted by Serratia …

In this paper, the importance of the forces governing the motion of a millimetre-sized sphere
in a viscous fluid has been examined. As has been shown previously, for spheres moving …

Telah dilakukan penelitian pengukuran modulus geser baja menggunakan analisis osilasi
pegasmassa. Tujuan dari penelitian ini adalah untuk mengetahui apakah metode analisis …

This study presents a classroom-friendly method for measuring the coefficient of viscosity of
a liquid using a smartphone's accelerometer sensor. A metallic ball tied with a spring–mass …

Drag is rarely taught in most undergraduate physics laboratory because it requires fairly
sophisticated equipment. In this study, we developed a laboratory unit studying both …

We discuss the motion of a harmonic oscillator using a state equation approach commonly
applied in a modern control theory (MCT) of engineering. Instead of a second-order …

This paper enlarges an undergraduate student project in non-holonomic mechanics (Janová
et al 2009 Eur. J. Phys. 30 1257–69) by considering rolling friction. In the original problem of …

To understand the phenotypical and aberrant aspects of brain functions, circuital elements
within the brain need to be perturbed and the effects correlated. However, the fast dynamics …

The dynamic behavior of a rigid magnetic sphere induced by an acoustic radiation force was
investigated. The sphere was suspended in water in a simple pendulum configuration. The …
