AB - Let $\Phi : H\rightarrow \mathbb {R}$ be a ${\mathcal {C}}^2$ function on a real Hilbert space and $\Sigma \subset H \times \mathbb {R}$ the manifold defined by $\Sigma :=$ Graph $(\Phi )$. We study the motion of a material point with unit mass, subjected to stay on $\Sigma $ and which moves under the action of the gravity force (characterized by $g>0$), the reaction force and the friction force ($\gamma >0$ is the friction parameter). For any initial conditions at time $t=0$, we prove the existence of a trajectory $x(.)$ defined on $\mathbb {R}_+$. We are then interested in the asymptotic behaviour of the trajectories when $t\rightarrow +\infty $. More precisely, we prove the weak convergence of the trajectories when $\Phi $ is convex. When $\Phi $ admits a strong minimum, we show moreover that the mechanical energy exponentially decreases to its minimum.
