If there was no friction then the ball would just slide instead of roll
because of the friction.
Gravity has a little effect on it. However the main force stopping the ball rolling is the friction force of the floor. The ball will stop rolling when the velocity of the ball is the sames as the velocity of friction force.
The ball rolls when you blow on it because of Friction.
Grass makes a ball roll slower then it would on a dirt surface. This is because the long grass blades cause more friction on the ball slowing it down.
Do you mean "What effect does friction have on the velocity of the ball?"
Static friction
Because of rolling friction, gravity, and fliuid friction (air)
Friction is when you roll a bowling ball down an bowling alley or when you kick a soccer ball. Hope this helped
because grass has more friction for ball to roll than dirt.
apply friction a rough surface cardboard for example, the rougher it is the slower the ball will roll but to much friction and it will stop altogether.
because friction acts on the ball.
