What is one way to overcome friction in a machine?
use lubricants it smoothens the surface and reduces the irregularity between both the surfaces resulting in reduction of friction
Do mountain climbers eliminate friction to overcome gravity to keep from falling?
Nope - they use friction to stop themselves from falling ! The various pegs, clamps etc rely on friction to hold them in place.
Why is climbing a greasy pole so difficult?
Because gravity keeps pulling you down, and the grease makes it difficult to use friction to overcome the pull of gravity.
Static friction is the friction force that must be overcome to keep an object moving at a constant speed?
Static Friction. "Just as the second law regarding friction states that surface area does not determine friction (but rather, weight determines surface area), the third law holds that friction is independent of the speed at which an object is moving along a surface-provided that speed is not zero. The reason for this provision is that an object with no speed (that is, one standing perfectly still) is subject to the most powerful form of friction, static friction. The latter is the friction that an object at rest must overcome to be set in motion; however, this should not be confused with inertia, which is relatively easy to overcome through the use of force. Inertia, in fact, is far less complicated than static friction, involving only mass rather than weight. Nor is inertia affected by the composition of the materials touching one another."
What does have more friction doormat or carpet?
doormat I think, because if we want to remove the dirt from our leg we want a thing that has more friction. So we use the doormat

What do engineers use to help reduce friction in the operation of a car?
organize you combustion chamber with carbohydrate rods and put friction pumps in the engine

What covers the body of bony fish and reduce friction when swimming?
These types of fish alway use MUCUS to cover their body, and to help reduce friction.
Why is a super sonic plane like it is?
Super sonic planes are extremely streamlined. this enables them to overcome a force known as 'Friction'. This is a force which slows things down. There are many types of friction but the type working on an airborne plane is known as 'Air Drag'. Streamlining helps on overcoming air drag. They are so streamlined that they use a parachute to help them slow down when they land.
Can friction be important?
when i am ask is friction important i say the answer is yes. friction is important and can help people in many different ways. like cars for a example cars use friction to drive on the road. there is many different types of friction to; dry friction, fluid friction, lubricated friction, skin friction, internal friction, ect..... all of these types of frictions can be different a different way.
What unit would you use to measure friction?
you would have to measure it with a scaleor a a thing you would way yourself.
What do animals use friction for?
Friction is a very helpful thing and with out it you couldn't move, speed up, slow down, change direction, bend, or twist. Without friction nothing would ever happen. Friction can oppose motion or it can make it difficult for an object to move across a surface. Friction both helps an hinders every thing we do.the object would not move without frictionThe friction acts in the opposite direction to that of direction of motion.So friction slows the object and if no external force is applied the object will come to stop.Friction is a force that opposes the direction of motion between two materials. It is parallel to the surface your object is touching. Friction depends on the coefficient of friction and the normal force (force exerted perpendicular to the surface your object is on; opposes gravity on a flat surface). There are two kinds of friction: static and kinetic. Static friction must be overcome in order to move an object. Once the object is in motion the friction acting on it is called kinetic. Static friction has a threshold of force that is needed to get the object moving but once the object is in motion it can be moved at a constant velocity with less force required.
Which parts of a bike use friction?
The brakes use friction to stop the bike and the tyres use friction to grip the road.
