Why does a ice-hockey puck have less friction than a ball rolling on the ground?

Ice has a much smoother surface than the surface of the ground, therefore there is less friction acting on the hockey puck compared to a ball rolling on the ground. Ice is nearly a frictionless surface.

What force is when a ball rolls across the floor?
The force that stopped it is a resistive force. Assuming there are no external force acting on it, Friction is the cause. When the ball is rolled, a force is applied. According to Newton's second law, F=ma, There is an acceleration, thus increase in velocity. At that same instance, when the ball moves, a natural resistive force, friction is produced. However at the next instance, there is no force pushing the ball, since friction exists when there is velocity, there will be a net force against the direction of travel. Thus generating a Deceleration. This happens till the ball comes to a stop, when it do not have any more speed. "Friction exists when there is motion" - this is a derivation from Newtons Third Law of motion. when the ball is moving it applies some force on ground so the ground also applies an equal and opposite force on the rolling ball. But since the vector component of the force on the ball that set it into motion is larger it keeps rolling till the time the Frictional force can bring it to an complete halt.
Role of friction in cricket?
To the bowler, friction is a great aid in determining the spin and bounce of the ball. And to a fielder when returning the ball. To the batsman - not much.Similar comments apply to baseball, Netball and basketball etc.
Why does a ball rolling on a carpet slow down and stop?
it is because the land is flat it has large surface area which experiences a large force of friction due to air and hence slows down
What causes a marble to roll?
Because of the force of friction pushing against the ball. The only way it could avoid that is if it wasn't rubbing against the ground and was instead closing floating in air, like the puck in air hockey. The air blowing up on it keeps the puck and the table from rubbing against each other and causing friction. :)
What is undulating plain?
Rolling (up and down- not flat) grassland. hillocks rather than full sized hills. many cowboy movies have them with the white ball rolling across the road
What causes a ball to stop rolling?
the friction and the motion of the ball both combined
What would happen if there was no friction between a rolling ball and the ground?
no
Why does a ball rolling on the ground slow down?
Friction from the air and ground will slow down the ball's motion.
What causes a ball rolling on the grown to eventually come to rest?
Friction - between the surface of the ball, and the ground.
What force slows and stops a rolling ball on the moon?
friction from the ground and the extremely light atmosphere
If a bowling ball and a soccer ball are rolling along the ground at the same speed the bowling ball has more of this because its mass is greater?
Friction
Does a ball rolling down a hill cause static friction?
Friction is one force causes a ball to roll downhill. The smaller the static friction coefficient, the more liable the ball will be to skidding instead of rolling. Static friction is involved in a ball rolling downhill.
What would happen if there were no friction between the rolling ball and the ground?
ball will just move without rolling, staying in it's initial position but moving indefinitely (that is if it is given an initial force).
What forces act on a rolling ball?
It acts as a rolling friction or rolling resistance when it starts to roll on a flat surface , it resists the direction of rotation of the object in both clock wise and anti clock wise direction.
What effect does friction have on a rolling ball?
If there was no friction then the ball would just slide instead of roll
What unbalanced force cause a ball to stop rolling?
Friction
What is good about frictional force?
friction is what slows everything down. if there was no gravity and you rolled a ball across the ground, then the ball would just keep rolling forever
