The motion of a block sliding on a curve is a well studied problem for flat and circular
surfaces, but the necessary conditions for the block to leave the surface deserve a deeper …

THE PHYSICS TEACHER◆ Vol. 58, January 2020 67 with a more realistic model where the
ball slips before falling off the large sphere. 2, 3 In fact, the tracks should be even a bit …

The problem of the classical motion of a round object is typically presented using idealized
setups in order to make it more tractable. Popular examples include a sphere moving on a …

We solve analytically the differential equations for a skier on a hemispherical hill and for a
particle on a loop-the-loop track when the hill or track is endowed with a coefficient of kinetic …

A small sphere placed on the top of a big static frictionless sphere, slips until it leaves the
surface at an angle $\theta_ {l}=\cos^{-1}{2/3} $. On the other extreme, if the surface of the …

The motion of a block slipping on a surface is a well studied problem for flat and circular
surfaces, but the necessary conditions for the block to leave (or not) the surface deserve a …

Supongamos ahora, que la cúpula presenta un rozamiento al deslizamiento de la partícula,
cuyo coeficiente cinético es μ. Vamos a determinar la velocidad v de la partícula en función …
