What is the method to ensure that an object slides continuously downwards without bouncing back up upon reaching the bottom?

The method to ensure that an object slides continuously downwards without bouncing back up upon reaching the bottom is to provide a surface with sufficient friction to slow down the velocity of the object gradually without stopping it abruptly. This can be achieved by using a surface that is not too smooth, such as a rough or textured material, or by placing a material with high friction, such as rubber, at the bottom of the surface. Additionally, one can also control the angle and slope of the surface to dictate the speed and trajectory of the object's descent, ensuring a smooth and continuous slide.
