Rotate friction refers to the resistance encountered when an object or component is rotated around an axis. This is commonly experienced in mechanical systems, where friction between moving parts can cause a decrease in rotational speed or make it harder to turn. Reducing rotate friction is important for efficiency and smooth operation of rotating components.

What type of friction does a pulley overcome?
A pulley overcomes static friction, which is the friction between the surface of the pulley and the rope or belt moving over it. This allows the pulley to rotate smoothly and lift objects with less force required.
Does static friction or rolling friction causes a car tire to turn on the road?
Static friction is responsible for causing a car tire to turn on the road. When the tire grips the road surface due to static friction, the torque generated from the friction allows the tire to rotate and propel the vehicle forward. Rolling friction comes into play once the tire is already in motion, helping to maintain its speed and stability.
What are the five ways force changes motion?
friction
Why do wheels need ball bearings to reduce friction?
Ball bearings reduce friction by allowing the wheel to rotate around an axle smoothly. The bearings distribute the load evenly, reducing the amount of friction between the moving parts, which helps the wheel spin freely and with less resistance.
Does a ball need friction to roll?
sure a ball needs friction to roll. the logic behind this being, that the friction which generally retards a body's motion plays differently in this case, it acts tangentially in backward direction at the point of its contact with the rolling surface, so in this way , it generates a rolling motion
In what ways can friction be helpful?
Friction is necessary for wheels to rotate and nails to keep in walls.

Why doesn't the ice rings around Saturn melt with the speed they rotate?
space is a vacuum. no air means no friction. without friction the ice doesn't melt
When is friction necessary for some type of movement to occur?
If a ball slides down a frictionless hill there will be no rotation of the ball. But with friction the ball will both translate and rotate down the hill.
How do you use friction daily?
Walking , if there is no friction you wont be able to walk properly . Another important thing is driving . In the absence of friction the car wheels wont be able to rotate probably thus the car will just go in circles.

What are the differences between live center and dead center in machining operations?
In machining operations, a live center rotates with the workpiece, reducing friction and heat. A dead center does not rotate and can cause more friction and heat buildup.

How friction can be both helpful and unhelpful?
Friction can be helpful because it allows us to walk, drive, and grip objects. It also prevents objects from slipping and helps to stop moving vehicles. However, friction can be unhelpful when it causes wear and tear on machinery, reduces the efficiency of moving parts, and generates heat that can be wasteful or pose a risk of fire.
