Neither. The ball rolls faster on cement, not grass, or dirt.
Varibles and controls for does a ball roll faster on grass or dirt
A ball will roll faster on carpet than grass or dirt because there are NO rocks or anything.
Dirt , assuming it is flat and dry . The answer depends upon the velocity of the ball and what resistance there is in either the dirt or grass .
It rolls faster on dirt because there is less friction on dirt to slow the ball down.
The answer is: Of course not! I would imagine it depends on the particular dirt and the particular grass though.
My answer is dirt I'd say dirt because the dirt is more flat than the dirt.Also,the grass has the leaves poped out so the ball will be faster on dirt......
Yes a ball roll is better on grass than dirt
On Dirt On Dirt
Dirt if there are fewer rocks, the grass blades act as extra friction and counter movers for the ball whereas a dirt path would have only the normal amount of resistance.
A ball can go further on grass than dirt because in dirt there are some rocks that can stop the ball.
The reason a ball rolls farther on dirt is because the grass has more potenial than dirt because once you roll the ball really hard the ball will slow down on grass and the grass is sometimes standing up and the dirt doesn't have any thing to stop the ball the dirt is is flat unlike the grass.
