Useful work lost to entropy.
according to wiki,
entropy = a thermodynamic property that is a measure of the energy not available for useful work in a thermodynamic process, such as in energy conversion devices, engines, or machines. Such devices can only be driven by convertible energy, and have a theoretical maximum efficiency when converting energy to work. During this work entropy accumulates in the system, but has to be removed by dissipation in the form of waste heat.
thus I think the previous answer used a complicated terminology in an over-simplified response.
Friction is usually referred to as a natural existing force against which a new opposing force has to be applied to achieve work
so when friction is present, more (usually man-made) force has to be applied to achieve the same work.
Generally computed as a coefficient of friction regarding the surface attraction between the surface the object is to be moved across and the object, and in computation is product of its mass & gravity
What else can I help you with?
What unit do you measure friction in?
you measure friction in Newtons
What unit of measure is used to measure friction?
The coefficient of friction is dimensionless.
What value of the coefficient of friction the greater the resistance to sliding?
The greater the coefficient of friction between two surfaces, the greater the resistance to sliding between them. The coefficient of friction is a measure of the amount of friction between two surfaces, with higher values indicating a stronger resistance to sliding.
Is friction a measure of the amount of force needed to move something a certain distance yes or no?
Yes. Friction is a force that resists the motion of an object moving across a surface. The amount of force needed to overcome friction and move an object a certain distance depends on factors like the roughness of the surfaces in contact and the weight of the object.
What are different ways to measure friction?
Friction can be measured using instruments like a spring scale to measure force required to overcome friction, or a friction tester to measure coefficient of friction between two surfaces. Friction can also be estimated by analyzing the wear patterns on surfaces or by calculating the energy lost due to friction during motion.
What is the relationship between the kinetic friction coefficient and the amount of force required to overcome friction between two surfaces in motion?
The kinetic friction coefficient is a measure of the resistance between two surfaces in motion. A higher coefficient means more force is needed to overcome the friction and keep the surfaces moving.
The measure of force required to move an object?
The measure of force required to move an object is known as the force of friction. Friction is the resistance that occurs when two surfaces come into contact with each other. The force of friction is influenced by factors such as the roughness of the surfaces and the weight of the object.
The amount of friction divided by the weight of an object forms a unitless number called the ... of friction?
coefficientThe amount of friction divided by the weight of an object forms a dimensionless number called the coefficient of friction.
What F is used to measure?
Friction
What properties affect the force of friction?
The nature of the surface. A measure of this is the coefficient of friction.
Can you prove that rolling friction is less than slidding friction?
Yes. Measure it.
What term is used to measure the aggressiveness of friction facing?
The term used to measure the aggressiveness of friction is coefficient of friction. It is a dimensionless value that represents the ratio of the force of friction between two surfaces to the force pressing them together.
