What else can I help you with?
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
Is static friction or sliding friction stronger?
Static friction is typically stronger than sliding friction. Static friction occurs when an object is at rest and needs to overcome the initial force required to start moving, whereas sliding friction occurs once the object is already in motion.
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 needs more force sliding a block or rolling it on dowels?
More force is typically required to slide a block on a surface compared to rolling it on dowels because sliding involves overcoming static friction, which is generally greater than the rolling friction experienced when rolling on dowels. Rolling on dowels allows for reduced friction due to the rotation of the dowels, making it easier to move the block.
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?
The force of friction needs to touch an object to have an effect. Friction occurs when two surfaces are in contact and one surface resists the motion of the other surface. It is this resistance that allows friction to have an effect on objects in contact.
Does a bicycle have to feel a force in the direction of its motion to go around a curve?
Yes, a bicycle needs a centripetal force acting towards the center of the curve to change its direction of motion. This force is typically provided by friction between the tires and the road surface, allowing the bike to maintain its trajectory around the curve without sliding out.
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.
When does friction need to be as high as possible?
Friction needs to be as high as possible when trying to prevent objects from sliding or when maximizing the grip between two surfaces, for example in car tires on a wet road or shoes on slippery surfaces.
Does a shoelase stay tied without friction?
no, they untie because of the force and friction between them
