What else can I help you with?
Do you have to overcome rolling friction when you slide a bag of groceries across the countertop?
If the bag is sliding across the countertop (i.e., the same surface of the bag is always in contact with the counter), then no. Rolling friction is only relevant when the surface of an object in contact with the surface it moves across always changes.
If you pull something with a force of 20N and the object is not accelerating what is the force of friction on the object?
The force of friction is equal and opposite to the applied force in this scenario, so the force of friction on the object would also be 20N. This allows the object to remain in a state of equilibrium and not accelerate.
What does converting sliding friction to rolling friction do to a system?
One way to show this would be to do the following experiment: Take a coil spring and tie two pieces of string to each end of it. Then tie one of the strings to something with wheels... preferably something whose wheels have a locking mechanism (maybe an office chair, a wagon, a bike). Pull the wheeled object by the string along a flat, level surface at a constant speed and note the elongation of the spring. Now try locking the wheels and pulling the object again in the same manner ... as long as circumstances are "normal" (i.e., you're not doing this on a skating rink or a floor covered in oil or something), it should feel harder to pull the object with the wheels locked, and the spring should elongate more as you pull it. If fact that the spring is elongating more when sliding demonstrates that there is a higher force of tension in the string pulling on it. The higher tension is caused by greater drag in the chair, which is in turn caused by sliding friction. Voila!
What might parachutists do to speed up their rate of fall?
They would have to reduce friction by becoming perpendicular to the ground and reduce their surface area.
What is the effect of less friction on an object?
Less friction on an object results in smoother and faster movement. It reduces the force needed to overcome resistance, allowing the object to move more efficiently and with less energy loss due to heat or wear.
What do you mean by nullifying friction?
To nullify means to eradicate or end something. Friction is a type of force. To nullify friction you would need to reduce the source that is causing the friction in the first place. Eg. If you have a rolling object there is friction. The faster the object the more intense the friction. Therefore if you stop or slow down the object you nullify the frictional force.
What does friction do to the object's motion?
The motion of the object might slow down or just change itself object would resist moving or keep moving. An object can have static friction, sliding friction, or rolling friction.
Does rolling friction push the same direction as the velocity of an object?
If it did, then any rolling object would speed up because of friction. Since everythingthat rolls actually slows down, the virtual 'force' of friction must be exactly oppositethe direction of an object's motion.
What is the definition for rolling friction?
Wheels, ball bearings, the Egyptians building the pyramids using tree trunks to move the stones. An example of rolling friction would be like a skateboard rolling on a sidewalk. car running up a hill. someone pushing a wheel barol A bowling ball
If an object is rolling down a hill friction acts in what direction?
Friction acts in the opposite direction to the direction of the sliding motion. In the case of an object rolling down a hill, the friction force would act against the direction of the object's motion, trying to slow it down or prevent it from sliding further.
Would walking impossible without rolling friction?
Yes it would, thank God for rolling friction
Tell you some apllications of rolling friction?
A wheel is an example of rolling friction. An example of rolling friction would be if you took kyle leary and folled him down a hill. his fat touching the grond would create rolling friction
Is static friction stronger than rolling and sliding friction?
It had better be! Otherwise, nothing could ever start sliding ... as soon as yourpull on the string becomes strong enough for the object to break free of thestatic friction and begin to slide, the force of kinetic friction would take over,and it would suddenly be even stronger!
What would happen if there was no friction when a tire was rolling on the ground?
It would keep rolling.
Why is a tire rolling on the ground rolling friction?
Friction is the resistance to sliding and as a tire rolls it does resist friction, otherwise it would slide.
How does rolling friction differ from sliding friction?
friction is a eorce of contact between two surfaces which opposes motion of objects over one another. In rolling friction the area in contact between two objects is comparatively less then that in case of sliding as in rolling, one object just roll over each other hence area of contact is less so force of rolling friction is less than sliding friction.
What is one example of rolling kinetic friction?
Anything with wheels, such as a car, would be an example of use of rolling kinetic friction.
