True
-It's "False"!

∙ 15y agoNo it can't. Static is usually larger than kinetic. However, they can be equal, one example being contact between surfaces like Teflon against teflon where there should be no friction. Static friction is the result of bonding of outer electron fields between surfaces. The force required to make the object move is the force required to break those bonds. Once moving (kinetic friction) the bonds can't reform as well so kinetic friction is lower. Static friction is greater because its the friction of objects at rest, which affected by inertia.

∙ 11y agostatic friction is the force that must be overcome to initiate an object's motion, ie. to get the object from still to moving. Kinetic friction is the force opposing a moving object, ie. it slows the moving object down.
Generally, static friction is higher than kinetic friction, ie. it is easier to push a moving object in the same direction than to push a still object.

Wiki User
∙ 9y agoYes. There is nothing in the definition that stops it from being greater than 1. In practice, it is usually lower, though.

∙ 13y agoSince this would make it possible to violate either the First Law of Thermodynamics or the Second Law of Thermodynamics, the answer is clearly NO.

The ratio of the resistance force to the effort force is called?
The ratio of resistance force to effort force is a mechanical advantage.
What kind of friction requires more force to overcome rollingfriction or sliding friction?
Coefficient of rolling friction will always be less than that of sliding friction. Hence more force is required to overcome sliding friction. Because the force = coefficient of friction x normal force (ie weight of the body)
Does ice has a higher coefficient of friction than rubber does?
Rubber has more friction than an ice cube. Ice has almost no friction what so ever.
Does coefficient of kinetic friction depend on weight?
Yes, It does not vary with lesser relative velocity between surfaces.But when the speed exceeds 10m/s ,due to heat produced between the surfaces the co-efficient increases.
What is the best summary of kinetic energy?
The best summary of kinetic energy is energy of motion. Kinetic energy is only present where there is motion in an object. Friction generates more kinetic energy.
What is more sliding friction or static friction?
static friction is higher in most cases, if you're talking about the coefficient of static or kinetic friction
How does the coefficient of static friction for two surfaces in contact compare to the coefficient of kinetic friction for the same two surfaces?
The coefficient of static friction is always larger because it takes more initial force to move an object that is at rest.
How do you calculate the coefficient of friction?
It's hard to guess that in advance, though as a general rule you can guess that smooth surfaces have a lower coefficient of friction than rough surfaces, and lubrication usually reduces the friction. However, to get more precise information, this has to be measured. Of course, you can first search the Internet - somebody may already have measured it.
Sliding kinetic friction or rolling kinetic friction?
need more information, please
Why kinetic friction is less than sliding friction?
there is more surface area contact with kinetic friction as opposed to sliding friction
What are some ways to increasing friction?
Use a surface that has a higher coefficient of static/kinetic friction and/or add more force downwards on the object.
Which type of kinetic fiction is usually greater sliding kinetic friction or rolling kinetic friction?
Sliding Kinetic Friction is usually greater than Rolling Kinetic Friction. Sliding Kinetic Friction is caused by two objects being dragged together, providing more opportunity for the objects' microscopic hills and valleys to catch.
What factors can effect the amount of friction between two objects?
The force of friction between two objects is the product of the normal force and the coefficient of friction. The normal force is the component of force that is perpendicular to the plane of friction. For example, if you are pushing on a block of wood on the floor with a force F at an angle of 30 degrees above the horizontal, then the normal force N = F sin 30. The coefficient of friction is specific to the two materials, in this example the block of wood and the floor. In addition, there is a static coefficient of friction (applicable to a stationary situation) and a kinetic coefficient of friction (applicable when the object is already moving).
What are the cause of friction?
Frictional forces are of two type 1-kinetic friction 2-static friction (keep in mind that in this article surface means a surface which cause some resistance to movement). I think static don't need details. So come on kinetic. Experimentally it is found that kinetic friction force is directly proportional to the magnitude n of the normal force acting on the body. The proportionality constant is 'coefficient of kinetic friction'.The nature of a surface is proportional to coefficient of kinetic friction i.e. If coefficient is low surface is slippery. Friction is caused by the degree of roughness a surface possess. The more the surface is rough, it cause more friction. Impetiments in surface as they make conact. Nothing is perfectly smooth that's has mass Friction is what is known as the resistance of a solid (in comparison to air resistance and water resistance). It is caused by two surfaces that are moving against each other being rough. This roughness means the surfaces are moving into each other as well as past each other, meaning some of the kinetic force is used up on the other surface. This will result in a loss of energy that will be given off as heat.
The ratio of the resistance force to the effort force is called?
The ratio of resistance force to effort force is a mechanical advantage.
How do you find kinetic friction without the coefficient?
by experiment. attach a pulley to the edge of a table. attach a known weight to a string through the pulley to another known weight on the table-top. put the particular surface who's coefficient of friction you wish to measure between the table top and the second known weight set on the table top. allow the first know weight to fall. measure its rate of descent. compare its rate of descent with that of the free fall acceleration of gravity for your particular latitude. you now have all the data you need to figure out the coefficient of kinetic friction. can you do that yourself or do you need to know more?
What kind of friction requires more force to overcome rollingfriction or sliding friction?
Coefficient of rolling friction will always be less than that of sliding friction. Hence more force is required to overcome sliding friction. Because the force = coefficient of friction x normal force (ie weight of the body)
