Abstract A loop-the-loop experiment is described to show how sliding friction affects motion of the ball. Conservation of energy can be used to explain the basic physics, but significant energy loss is observed in practice and expands the usefulness of this apparatus as a teaching tool.

By relying on the complete similarity of an accelerated coordinate system with a gravitational field, a simple accelerated loop-the-loop is described, by which a ball starting at the bottom rolls backward up over a loop and is caught at the top. Simple means of accelerating the apparatus suffice.

Looping the Loop: The African Vector in Hispanic Transatlantic Studies
2019This article examines the presence and absence, visibility and invisibility, of Africa from formulations of the trans-Atlantic focused on Latin America and the Caribbean. It critiques a long naturalised Ibero-American loop that tends to sidestep triangular and rhizomatic configurations and argues, amongst other things, that Spain’s colonization of the ...

DNA looping is widely used in nature. It is well documented in the regulation of prokaryotic and eukaryotic gene expression, DNA replication, and site-specific DNA recombination. Undoubtedly looping also functions in other protein-DNA transactions such as repair and chromosome segregation.

Energy considerations give an incorrect value for the minimum height from which a sphere may be released on the approach track of a loop-the-loop, assuming that the sphere rolls without slipping. Analytical and graphical methods are described for predicting whether the sphere will negotiate the top of the circular loop for arbitrary conditions of ...
