It usually take more force to start an object sliding than it does to keep an object sliding because static friction is usually than sliding friction?
usually greater than the sliding friction
What is slididng friction?
Static friction is the side force between objects that needs to be overcome to move it; sliding friction is the side force between objects that needs to be overcome to keep it moving once it starts to move, and is generally lower than static frictionmove it
What are the 3 kinds of friction describe each?
sliding friction is like sliding a desk without wheels across a floor since its sliding and if there a large amount of weight involved it will be harter to over come the friction , rooling friction is like a skateboard rooling down the street for rooling friction the object NEEDS to have wheels or it wouldn't be rooling friction,and fluid friction is like droping a ball through air since air has water particles and counts for fluid friction.
Why does sliding large books take more force than sliding small books?
Sliding large books requires more force than sliding small books because larger books have more mass and surface area, leading to increased friction with the surface they are sliding on. This increased friction makes it harder to overcome the resistance and slide the large books.
What is the definition of kinetic or dynamic friction?
Kinetic friction is commonly thought of as the friction between two objects while those two objects slide against each other. To determine the coefficient of kinetic friction (for an object under the influence of gravity on some surface), one needs to determine the angle at which the sliding object moves at a constant speed down the other object (think of a flat piece of rubber sliding down a flat plank of wood). This is different from static friction where the sliding object has some applied force to move along a surface, but that object is stationary because of the friction applied by the surface. To determine the coefficient of static friction, one needs to determine the angle at which the sliding object begins to move down the surface.
Which force needs to touch something to have an effect?
friction.
Who needs a bigger force to keep them moving a man or a child?
It depends. If you want to lift them up, you have to act a force equal to their weight, so a heavier person would need a force with greater magnitude. If you want to move them horizontally on a plane with friction the heavier person needs a force with greater magnitude again. On a plane without friction no force needs to be acting on them in order to move.
What keeps cartilage slippery?
because it needs to be able to reduce friction between bones
Walking would be impossible without friction?
Yes, your foot needs contact with the ground to walk, because it pushes itself off of the ground. With no friction, your foot could not stay on the ground to push off. It's similar to walking on ice except... impossible.
What force could cause a moving object to stop?
Any force acting in the direction opposite to that of the motion. It could be a braking force, or drag (resistance from the fluid in which the body is moving), or friction (resistance from the body along which it is moving)
What happens if you put transmission oil into your engine oil?
You definitely need to change the oil as the Trans Fluid is much thinner and doesn't do the same job engine oil does .Further, the lubrication properties are very different. ATF-Automatic Transmission Fluid- needs to TRANSFER a lot of 'momentum', that is, the torque converter needs a fluid that is somewhat heavy but of very thin viscosity, therefore that kind of fluid can by used to transmit a lot of force thru the converter halves, and do it without a heavy friction (viscosity) looses. Friction reducing needs are second nature.Engine oil has a completely different set of requirements: friction reduction primarily, cooling and a cushioning effect. Therefore, those two liquids have to be very different.Placing more than a few ounces of ATF into the engine crankcase will destroy its properties, risking the engine. Complete flushing and correct engine oil replacement is mandatory! amclaussen.
How friction influenced the invention of the bicycle?
Tires, grips, pedals and brakes needs to have high friction, while all rotating parts needs to have low friction.
