As long as the bearing is placed somewhere where it will roll in the desired motion of the object. The point of bearings is to create the least contact possible between the object being moved and the bearing.

Ball bearings are types of rolling-elements bearings that carry loads and position moving machine parts while facilitating motion. Ball bearings consist of four major parts which are: 2 rings/races, the balls (the rolling elements), and the retainer (the ball separator).
A high-quality ball bearing is a precision item. The rings and balls are machined to precise tolerances and roundness. The balls and ball tracks (or raceways) are highly polished to ensure that the bearing rotates smoothly and easily. Frictional torque, or turning resistance in layman's terms, is extremely low.
Bearings with no lubrication have the lowest turning resistance, but steel ball bearings should be lubricated unless turning speeds are extremely low. They can be lubricated with a low torque instrument oil, but depending on speed and operating time, they may require constant lubrication with an oil bath, jet, or spray. A shielded bearing pre-lubricated with a finely filtered, low torque grease to provide a constant film of oil between balls and raceways while also helping to radiate any heat away from the points of contact is a simpler alternative.
Imagine the heat, vibration, turning resistance and rapid wear that would result from rotating a steel shaft, at speed, in a steel housing without the use of bearings. The noise and the excessive amount of steel debris would soon let you know that something was wrong. We have come a long way from the days of packing grease or fat between wooden cart wheels and axles to reduce friction and with constant advances in manufacturing and steel and lubricant technology, the number of low friction options for a wide variety of products continues to grow.

How to reduce frictional force?
Lubricate the join between the two objects that are causing friction. If its friction with the air, make it more aerodynamic.
More friction between water and streambed will reduce the speed of flowing water?
true
What does reduce the force of friction mean?
it means enabling a substance to move more frequently on a surface a friction is a force which resists the movement of an object
If you had a slippery floor would adding polish create more or less friction?
Polish would most likely smooth the surface creating less friction and making it more slippery.
What are 4 ways to reduce friction?
Decrease area of contact utilize lubrication utilize alternate materials Reduce speed decrease mass or gravitational force being applied
What are the ways in which friction is reduce on aeroplane?
by giving it better aerodynamics you can reduce friction. but also the faster it goes the more friction it gets.
Advantages of journal bearings in contrast with anti friction bearings?
Generally, journal bearings have higher friction factor, consume higher energy and release more heat, but they have larger contact surface, so normally used in low speed high load applications.
Is this true or false the handlebar of a bicycle is an example of using a wheel and axle to reduce the amount of force a rider needs to turn the front wheel?
Something is a bit confused here.The handlebars are levers that are used to turn the front wheel. It would be much more difficult to steer the bicycle just using the fork steering tube.The front axle and bearings essentially reduce the friction verses, say sliding/dragging the front wheel forward.High quality bearings, bearing races, and grease reduce the rotational friction and thus reduce the amount of energy required to turn the front wheel.
How ball bearings work to reduce friction?
Ball bearings are essential components of many machines and devices we use in our daily lives. They are found in cars, bicycles, washing machines, and even skateboards. They are designed to reduce friction and increase the efficiency of the machines they are used in. In this article, we will explore how ball bearings work and how they reduce friction. Firstly, let's define friction. Friction is a force that resists motion between two surfaces in contact. It is a natural phenomenon that occurs when two surfaces rub against each other. Friction can cause wear and tear on the surfaces, which can lead to damage over time. It also reduces the efficiency of machines by wasting energy as heat. Ball bearings reduce friction by replacing sliding friction with rolling friction. In a typical system, a shaft rotates inside a housing. Without ball bearings, the shaft would be in direct contact with the housing, creating friction that would slow down the rotation and create heat. However, with ball bearings, the shaft rests on a series of small balls, which roll around in a circular track between the shaft and the housing. This rolling motion creates less friction than sliding, allowing the shaft to rotate more smoothly and efficiently. The balls in a ball bearing are usually made of steel, ceramic, or other materials. They are precision-made to be perfectly round and uniform in size. This is essential for ensuring that the balls roll smoothly and do not jam or create additional friction. The raceway or track on which the balls roll is also critical to the performance of the ball bearing. The raceway must be precisely machined to ensure that the balls roll smoothly and do not slip or wobble. The quality of the raceway can affect the durability and efficiency of the ball bearing. The cage or retainer that holds the balls in place is another important component of a ball bearing. The cage keeps the balls evenly spaced and prevents them from colliding with each other. This allows the balls to roll smoothly and reduces the chances of the bearing jamming or failing. One of the key advantages of ball bearings over other types of bearings is their low friction. Because the balls roll rather than slide, they create less friction and therefore less heat. This reduces wear and tear on the bearing and increases its durability. It also makes the machine more efficient by reducing energy loss through friction. Another advantage of ball bearings is their high precision. Because the balls are perfectly round and uniform in size, they can rotate at high speeds without creating excessive vibration or noise. This makes them ideal for use in machines that require high precision and reliability, such as in aerospace or medical applications. In conclusion, ball bearings reduce friction by replacing sliding friction with rolling friction. They do this by using precision-made balls that roll smoothly in a precision-machined raceway. This reduces wear and tear on the bearing and increases the efficiency of the machine. Ball bearings are essential components of many machines and devices we use in our daily lives, and their low friction and high precision make them an ideal choice for many applications.

Why do use powder on a carom board?
the main reason for doing so is that the surface becomes smooth n in terms of science to reduce "friction" that wud exist between the board n the striker due to which it will move more swiftly with lee deployment of power..!!
