yes there is it.
Not sure if you mean 2 types of friction. Two types of friction can be just friction with the ground, and air friction such as drag on any vehicle, or any type of flying machine. Other objects can have air friction too, but not as much as something moving at a higher rate of speed.
Friction is most commonly known as any push or pull. There are four types of friction ; sliding friction, static friction, rolling friction, and fluid friction. Sliding friction is when something is sliding against another surface. Static friction is when there is force being applied upon a heavy object or the object is being moved on a rough surface. Rolling friction is when something is rolling on a surface and friction slows it down. Finally, fluid friction is when an object is being slown down on or in water, air, or any others fluid.
Limiting friction is the case of static friction where an object is right on the edge of moving, any more force applied to the object will cause it to move. Limiting friction is the largest value that the static friction can take
Static friction force is the force that opposes the initiation of motion between two surfaces and can vary in magnitude up to a maximum value. Rolling friction force is typically lower than static or sliding friction, as it involves the resistance to rolling motion. The specific forces depend on various factors such as the roughness of the surfaces, the magnitude of the normal force, and any lubrication present.
it is sliding friction,because you slide the brish down to your hair.
my theory is tht the friction between the earth and sun is equal and thus earth has a single orbit which does not change , instead the planet rotates around itself and revolves around the sun, not because of their equal friction but because of its mass being less compared to the sun.
No.
There is 'skin friction' also know as drag. There is also lubricated friction.
Internal combustion, friction and sometimes the sun.
limiting friction will slow an object more than any other type of friction
With the sun... *smile* and a loupe.
Ice skating does not require any friction because the skater needs to glide on the ice and if there was any friction on ice the skater would have trouble to skate smoothly on the ice. That is why ice skating does not require any friction at all from my perspective.
the four types of friction are static friction,sliding friction,rolling friction,and fluid friction Static friction is friction between two solid objects that are not moving relative to each other. Fluid friction is with any kind of liquid or glass. sliding friction is when a surface slides on another surface. Rolling friction is when you are moving with wheels.
There's friction between any 2 contacting surfaces.
Because if there wasn't any friction, nobody could be stopped. You wouldn't be able to Rollerblade, or play almost any sports. If there was no friction, you wouldn't be able to hear a lot of musical instruments!
Friction
yes there is friction in winter because without any friction we wouldn't be able to walk and the cars would slide and never brake
