How ball bearing reduce friction?
Bearings reduce friction by providing smooth metal balls or rollers, and a smooth inner and outer metal surface for the balls to roll against. The smoothness of the metal reduces the friction and the surface area.
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.
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.
What kind of golf balls should you buy?
Dimpled golf balls because they fly farther than smooth ones. (I don't even know where to buy smooth ones). :P
Why do you use casters or bearings to move an object?
Casters and bearings reduce friction and make it easier to move heavy objects by allowing them to roll smoothly on wheels or balls. This design helps distribute the weight evenly, making it more efficient to push or pull the object.
Do balls have friction on dry soil?
Yes, balls experience friction on dry soil as they roll due to the interaction between the ball's surface and the soil particles. The amount of friction depends on factors like the type of ball, the surface texture of the ball, and the properties of the soil.
How can you show that momentum is not conserved between the balls when friction is strong?
If momentum is not conserved between the balls when friction is strong, you can show it by performing an experiment where two balls collide on a rough surface. Measure the momentum before and after the collision and observe if the total momentum changes. If the momentum changes, it indicates that momentum is not conserved due to the influence of strong friction during the collision.
Will a warm wash cloth make your balls smooth?
washing machicne
What do you do if you get nair on your testacals?
wash it off and enjoy your new smooth balls
What does friction have to do with newton's cradle?
Friction between the balls in Newton's Cradle can dampen the energy transfer between them, causing the balls to eventually stop swinging. This frictional force can also cause the balls to lose momentum with each collision, affecting the efficiency of the energy transfer through the system.
Does friction change the moving direction?
It certainly can.What happens when your car is rolling along down the street and the tires on one sidehit a rain puddle in the gutter ? That side gets slowed by friction with the water, and thecar pulls toward that side.And let's not even get started on bowling balls headed down the lane.http://wiki.answers.com/Can_friction_change_the_direction_of_an_moving_object&action=editBut please note that a single object, such as ball, cannot change its direction due to friction alone. Friction is only a force that opposes motion, not a force that causes motion.
How is fluid rolling sliding and static friction increased?
The resistive forces of each of those types of friction except for fluid friction depend on both the normal force (exerted on the object by the surface that it's on) and the friction coefficient that corresponds to that type of friction. So naturally we'd increase the force of friction by increasing either or both of those factors. The friction coefficent can be increased by making the surfaces "rougher" so that more of the energy is lost by being turned into heat and/or sound. We can also increase the normal force to increase the force of friction. The most straightforward way is to make the object heavier so that the supporting surface pushes harder against the object, increasing the force of friction. It's important to know that the the normal force decreases when the surface becomes increasingly slanted. For example, an object dropped against a wall is not being held up by the surface at all so there's no normal force. So we can increase the force of friction by making sure that the surface is completely parallel to the ground. That way, the surface is supporting the entire force due to gravity acting on the object. We can also be extreme by changing the "apparent weight" of the object. If the object is on a surface that's accelerating upwards (like an elevator), the force of friction will be higher than normal because the surface will be pushing even harder against the object. For each of the individual friction types, there are some differences. Sliding and static friction are similar to each other. On the other hand, rolling friction often depends on internal friction in the wheel bearings. That's why bearings often use balls to minimize contact area and are well-lubricated. Fluid friction increases with velocity and depends on how viscous the fluid is. The exact relationship between velocity and drag depends a lot on the geometry and speed of the object.
