sure a ball needs friction to roll. the logic behind this being, that the friction which generally retards a body's motion plays differently in this case, it acts tangentially in backward direction at the point of its contact with the rolling surface, so in this way , it generates a rolling motion
Friction between the ball and the surface it is rolling on will slow down the ball's motion by converting some of its kinetic energy into heat. As a result, the ball will roll for a shorter distance and with a lower speed compared to a scenario with minimal friction.
A ball with less friction, such as a smooth, hard ball like a metal ball or a marble, will typically roll the farthest down a ramp compared to a ball with more friction, such as a rubber ball or a soft foam ball.
The force that makes a ball roll is the force of friction between the ball and the surface it is rolling on. As the ball moves, friction between the ball and the ground pushes the ball forward, causing it to roll. Additionally, any initial force applied to the ball (like giving it a push) can also contribute to its rolling motion.
The ball with the least amount of friction will roll the farthest. This typically means a ball with a smooth and spherical surface. The surface on which the ball is rolling will also affect its distance.
If you roll a ball on a surface with very little friction, the ball will travel much further than if it were on a high-friction surface. The ball will roll smoothly with minimal resistance, conserving its initial momentum and velocity for longer distances.
because of the friction.
The ball rolls when you blow on it because of Friction.

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.

A ball will typically roll faster on dirt compared to grass, as dirt provides less resistance and friction than grass. Grass can create more friction which can slow down the ball's movement.
If you roll a ball on a surface with very little friction, the ball will travel much further than if it were on a high-friction surface. The ball will roll smoothly with minimal resistance, conserving its initial momentum and velocity for longer distances.
If friction decreases, the ball will roll farther since there is less force resisting its motion. Friction between the ball and the surface slows it down, so reducing friction allows the ball to maintain its speed and travel a greater distance.
The two types of friction that occur when rolling a ball from the top of a hill to the bottom are kinetic friction between the ball and the surface it rolls on and air resistance as the ball moves through the air.
