Why is friction low on snow?
Yes.
Jack is going skiing does he need high or low friction between his skis and the snow?
low friction
Why is our 1997 mercury mountaineer sliding in snow?
unfortunately the coeficient of friction between rubber tires and packed wet snow is so low that the inertia of the vehicle allows the vehicle to slip on the snow. Deeper snow or snow tires will increase the friction slightly and allow you to move in the direction of your choosing.
How is low friction useful in your life?
Friction can be very useful in your life. You need low friction when you ski. If you have high friction you cannot glide easily on the snow. You can also use low friction when you ice skate. If you have high friction you cant glide across the ice. When you use your laptop your keypad has to be able to glide. Some examples of high friction are erasing with your pencil, rubbing your hands together etc.
What can hydrofoil be used for in beauty?
Hydrofoils are boats that skim on top of the water with very low friction similar to jet skis. Steering is accomplished by a rudder submerged in the water. They are not used for beauty.
What reduces friction between two pieces of metal?
Something with a low coefficient of friction such as PVC or PTFE polymers
Riction between two flat surfaces can be divided into two categories What are the two most common kinds of friction?
High friction and low friction.
Does a hoover have high or low friction?
it is low friction i think
An example of two surfaces that have a low coefficient of friction?
human joints are an excellent example. they have a static friction coefficient of .01 μs and a kinectic friction coefficient of .003 μkanother good example would be waxed wood on dry snow (as in a snowboard on a ski slope) this has a static friction coefficient of .04 μsHope this helped!
Why is friction impotant when you walk?
If there were no friction between your soles and the pavement, you would be unable to apply the force needed to walk forwards. Think how difficult it is to walk on ice where the friction is low.
What are the factors which affect the coefficient of static friction?
Dry surfacesFor low surface pressures the friction is directly proportional to the pressure between the surfaces. As the pressure rises the friction factor rises slightly. At very high pressure the friction factor then quickly increases to seizingFor low surface pressures the coefficient of friction is independent of surface area.At low velocities the friction is independent of the relative surface velocity. At higher velocities the coefficent of friction decreases.Well lubricated surfacesThe friction resistance is almost independent of the specific pressure between the surfaces.At low pressures the friction varies directly as the relative surface speedAt high pressures the friction is high at low velocities falling as the velocity increases to a minimum at about 0,6m/s. The friction then rises in proportion the velocity 2.The friction is not so dependent of the surface materialsThe friction is related to the temperature which affects the viscosity of the lubricant
What does volleyball have to do with friction?
actually volleyball has alot to do with friction. when you are getting ready to hit the ball there is friction between the floor and your feet. then, when you hit the ball there is friction between your feet and the floor but also between your hands and the ball. now is the ball goes low and you hit it you would be using alot of friction because there would be friction between your body and the floor, the volley ball and your hands and maybe the ball and the floor. hope this answers your question!
