In this paper we describe all the constant-speed ramps for the case F(r) = -m/r. We show the circles and the logarithmic spirals play an important role. Not only they are solutions but every other solution approaches either a circle or a logarithmic spiral.}, organization = {MTM2017-89677-P, MINECO/AEI/FEDER, UE}, keywords = {Ramp}, keywords = {Central force field}, keywords = {Friction force}, keywords = {TreadmillSled}, title = {Constant-speed ramps for a central force field}, doi = {10.3934/dcds.2021003}, author = {López Camino, Rafael and Perdomo, Óscar}, }
