Say tennis for example when there is a strong gust of wind the ball could change its direction or it could be harder to hit
volume: obviously unaffected mass: could change, depending on what the hardening method was density: would only change if the mass did hardness: obviously copied
Because the hard surface doesn't absorb any of the energy of the tennis ball - thus the ball bounces higher than if it was dropped on a softer surface.
It is quiet hard. It has a cork centre, covered by leather. So it is harder than a tennis ball, but not as hard as a Baseball ball or a cricket ball.

In some ways in tennis i may help you hit the ball harder. same with baseball or you may be able to throw the ball harder.
Get hit by one and tell me. A baseball is relatively hard, but not as hard as a golf ball, but harder than a tennis ball.
Yes, the weight. The lighter the tennis racket, the lighter you hit the ball. The heavier racket can hit harder shots.
i wouldn't say so. i have played softball for most of my life and tennis takes hitting the ball over a fence but softball and baseball require hitting the ball, ptching, and fielding.
The air inside the ball expands on heating and this, in turn, makes the ball harder / more elastic.
