There are two types of drag experienced by a sphere. The first is the obvious drag due to friction. This only accounts for a small part of the drag experienced by a ball. The majority of the drag comes from the separation of the flow behind the ball and is known as pressure drag due to separation. For laminar flow past a sphere, the flow separates very early. The surface roughness caused the flow to transition from laminar to turbulent. The turbulent flow has more energy than the laminar flow and thus, the flow stays attached longer.

Is there friction when a toy car rolls down a ramp?
Yes Friction between the wheels and the ramp and also friction between the body of the car and the air (unless the car and ramp are in a perfect vacuum) There will be additional friction in the bearings or ball race of the wheel / axle too
Why does the ball decrease in height every time?
The two main reasons are (1) the collision is inelastic and (2) friction. Both these factors reduce the ball's energy.
A rolling ball will eventually stop rolling why does it do that?
It will not, unless it is acted upon another force. If it's rolling on something, then friction will stop it (the ball rubbing on the table slows it down).
Why does a ball stop rolling on rough road sooner than on a smooth road?
Because the rough road has more friction, thus expending the balls energy quicker than smooth road with less friction.
The speed of ball increases as it rolls down an inclinem What happens to its speed on a smooth horizontal surface?
It's speed will reduce to to friction by gravity.
What effect does friction have on a rolling ball?
If there was no friction then the ball would just slide instead of roll
If friction did not exist and you rolled a ball on the floor what would the ball do?
The ball would just keep rolling on.
What does volleyball have to do with friction?
actually volleyball has alot to do with friction. when you are getting ready to hit the ball there is friction between the floor and your feet. then, when you hit the ball there is friction between your feet and the floor but also between your hands and the ball. now is the ball goes low and you hit it you would be using alot of friction because there would be friction between your body and the floor, the volley ball and your hands and maybe the ball and the floor. hope this answers your question!
What causes a ball to stop rolling?
the friction and the motion of the ball both combined
What force happens when you throw a ball?
The resistance the ground has on the ball causes it to slow down and this force is called friction. Ice has little friction which is why the ball would have rolled further on ice for instance.
Which is an example of sliding friction a cars wheels rolling down the road a bird flying through the air a child applying the brakes on his bike a bowling ball rolling down a lan?
child applying brakes
Friction always acts in a direction?
Friction always acts in the direction opposite to the the motion of the object.For example, if a bowling ball rolls to the right, friction would act to the left.Without friction, if you threw a ball, it would keep going forever. Friction slows objects down.
What would happen if there was no friction between a rolling ball and the ground?
no
Why is friction important in bowling?
then you would not be able to grib the ball
Would friction or air pressure affect how fast a ball rolls down a incline?
Yes it would. Speed will depend on Weight of the ball, Incline angle, Friction, and air pressure.
Does fluid friction affect soccer balls?
All friction affects a moving object, the source of the friction and the object moving is irrelevant. Water on a soccer ball would effect the performance of the ball.
How is friction useful to netball players?
Friction keeps you from flying off the court.
