* Elasticity: Rubber is much more elastic than wood. This means it can deform and absorb more energy when it comes to a stop. The rubber ball will "bounce" back, dissipating energy in the process. Wood, on the other hand, is less elastic and will transfer more of the energy directly to whatever stops it, making it feel harder to stop.

* Friction: Rubber has a lower coefficient of friction than wood, meaning it creates less resistance when sliding against a surface. This means a rubber ball will lose energy through friction more slowly than a wooden ball.

In simpler terms: Imagine trying to stop a bouncing rubber ball versus a wooden ball. The rubber ball will bounce back and lose energy with each bounce, making it easier to stop eventually. The wooden ball will have a more direct impact, transferring more of its energy to your hand, making it feel harder to stop.
