What make a moving ball come to rest in a while even if no force is applied?
Friction with the surface it is rolling on and wind resistance against the mass of the ball. Both are forces that will eventually bring the ball to a stop.
What would happen to a boat that was moving upstream at the same speed as the current moving downstream?
The boat would make no progress.
What role does friction play when moving a heavy object?
It can make moving heavy objects easier for example sliding friction you can slide it or rolling friction you can roll the object across some kind of round cylinders or even fluid friction with water running under the object can make it easier.
What is the magnitude of the impulse on an 7.2 ball rolling at 1.2 when it bumps into a pillow and stops?
First of all the grammar in this question is atrocious. Second, this question can not be answered because there are missing 'given' facts. The ball is 7.2, in what type of measurement? It could be inches, feet, in metric and so on. The same goes for the ball rolling at 1.2, 1.2 what? Once again, inches, feet, in metric and so on. So the answer is 0 because there is not enough information to make a determination.
Will grass make a basketball bounce?
No,of course not, the friction between the basketball and the grass would make the ball bounce less.
What make a moving ball come to rest in a while even if no force is applied?
Friction with the surface it is rolling on and wind resistance against the mass of the ball. Both are forces that will eventually bring the ball to a stop.
How do ball bearings work?
Ball bearings use tiny balls to maintain separation between moving parts of a load bearer. They are effective because they are very cheap to make, and the rolling balls reduce friction between the moving parts of the bearing.
How do you make a disco ball in transformice?
It is impossible, though if you wanted to make a moving ball or a ball with moving squares, it could work.
How do you make the marble ball go down hill slower?
We can use astoterf on hill to slow the marble
Is saying hi to a person a good way to make a friend?
Its not a great waч, but it starts the ball rolling. Maчbe doing someone a favour would help ? Or opening the door for them when their hands are full ? There are lots of different waчs and "hi" is a good waч to start the ball rolling. Hope this has helped. Jessica.Elizabeth
Is the batter out if he inadvertently make contact with a slow rolling ball in foul territory?
If the ball is in fair territory, the fact that the fielder is standing in foul territory does NOT make the ball foul. the same as if a ball is foul, the fielder standing in fair territory doesn't make the ball fair.
Why does a cricketer take a catch a ball by moving his hands in the direction of the motion of the ball?
to reduce the impact, and make it hurt less.It has to do with the retarding force that would be exerted by the ball on the hand if the hand were to just stop it - the force would be high since the ball's motion is stopped immediately. But by moving the hand in the direction of the motion of the ball, it allows the velocity of the ball to decrease in a longer interval of time (and so, causes the retarding force to decrease). This means that the force exerted by ball on the hand is much lower, and the fielder does not get hurt.
How many turns would a tennis ball make if it were rolled from one end of a tennis court to the another?
Ball diameter = 2.63ins 78 feet X 12 (inches) Court length And pi = 3 1/7 C of ball = 8.26346 inches Court length = 936 inches Therefore the number of revolutions rolling along a sheer surface of a court = 113.2697 (all approximate, of course!) So there would be roughly 113 complete 'turns' of the rolling ball from baseline to baseline
Does rolling friction occur in basketball?
Drag and friction has a curving effect on a golf ball. The ball may make a curved trajectory as it flies through the air, mostly taking the direction of the wind.
Why is there a ball in a whistle?
The ball is there to make the whistle tone more noticeable. It does so by moving around, raising and lowering the pitch and volume as it moves. The result is much more attention-grabbing than the flat tone that would come from a ball-less whistle.
How does the dampness of the ground effect how an outfielder should play?
The dampness of the ground can make the ball stop rolling, so that the outfielder would have to play further in, but the dampness also affesct the outfieldsers ability to get to the ball, so he needs to play conservatively. Also, the sampness cold make the ball skim over the top and wuickly passed the fielder, but this is less likely.
Is it true that if you slide a bag of groceries along a countertop you must overcome rolling friction?
Rolling friction results from momentary attractions between a rolling object and the surface it is rolling on, so as long as the same surface of the bag is always facing the surface, as is usually true for sliding, there is no rolling friction to consider.However, for sliding, there are two different values for friction: the static value, which is how much force must be applied to a resting object to start moving it across a surface; and the dynamic value, which is how much force must be applied to a moving object to make it keep moving with the same velocity.
