The resistive forces of each of those types of friction except for fluid friction depend on both the normal force (exerted on the object by the surface that it's on) and the friction coefficient that corresponds to that type of friction. So naturally we'd increase the force of friction by increasing either or both of those factors. The friction coefficent can be increased by making the surfaces "rougher" so that more of the energy is lost by being turned into heat and/or sound.
We can also increase the normal force to increase the force of friction. The most straightforward way is to make the object heavier so that the supporting surface pushes harder against the object, increasing the force of friction. It's important to know that the the normal force decreases when the surface becomes increasingly slanted. For example, an object dropped against a wall is not being held up by the surface at all so there's no normal force. So we can increase the force of friction by making sure that the surface is completely parallel to the ground. That way, the surface is supporting the entire force due to gravity acting on the object. We can also be extreme by changing the "apparent weight" of the object. If the object is on a surface that's accelerating upwards (like an elevator), the force of friction will be higher than normal because the surface will be pushing even harder against the object.
For each of the individual friction types, there are some differences. Sliding and static friction are similar to each other. On the other hand, rolling friction often depends on internal friction in the wheel bearings. That's why bearings often use balls to minimize contact area and are well-lubricated. Fluid friction increases with velocity and depends on how viscous the fluid is. The exact relationship between velocity and drag depends a lot on the geometry and speed of the object.
static, rolling, fluid, and sliding friction
sliding friction is less than static friction. it is also very easy to move better than static friction.
static sliding has a much greater force then rolling friction cause it covers more area
There are three types of friction, static friction, rolling friction, and sliding friction. Static friction is friction between two surfaces that aren't moving relatively to each other. Rolling friction is friction between a rolling object and the surface that it is rolling on. Sliding friction is friction where an object slides, or rubs against, another surface.
There are four types of friction: Fluid Friction (The friction caused by falling through air or water, or any other liquid etc), rolling friction (Like a ball rolling across the floor), static friction (The force it takes to begin something's movement), and sliding friction(Like pushing a box across the floor). In order of strongest to weakest it's Static, Sliding, Rolling, Fluid.
static, rolling, fluid, and sliding friction
true
sliding friction is less than static friction. it is also very easy to move better than static friction.
i think it it rolling friction
static sliding has a much greater force then rolling friction cause it covers more area
Sliding Static Fluid Rolling
Friction is a force between to surfaces that resists motion. Static friction is the resistance to motion when two surfaces are not moving relative to each other. Sliding friction is the resistance to motion when two surface are sliding, one over the other. Sliding friction is less than static friction for the same two surfaces. For rolling friction an object is rolling, like a tire on a road. It's what provides traction between the two and makes the car "go." For a tire on a road, rolling friction is less than sliding friction.
Typically not. However rolling friction is somewhat of a myth. Rolling friction is actually caused by static friction. There are really only two types of friction: Static and Kinetic. That's it! Rolling friction is caused by static friction and the coefficient of friction (which determines its strength) is dependent upon the two materials of interaction.
