The relationship between the coefficient of kinetic friction ( denoted as uk ) and the mass, surface area, type of material or the speed of the object, is that the uk between a moving object and a non-moving object affects and distributes it on every points of an atom or molecule in all regions of both of the surface area of the two objects in contact with the object in motion, also the material from the object in motion relatively in contact to the surface of the other object which is not moving at all, determines the speed of the object, whether the material is rough that has lesser speed than that of a smooth surface or smooth vice versa.
What else can I help you with?
When the block of mass is increased is there an increase in the value of coefficient of kinetic friction?
No, increasing the mass of the block does not directly affect the coefficient of kinetic friction. The coefficient of kinetic friction depends on the nature of the surfaces in contact and does not change with mass.
What is the coefficient of friction of frac sand?
The coefficient of friction of frac sand varies depending on factors like particle size, shape, and moisture content. On average, the coefficient of friction for dry frac sand on steel surfaces is around 0.6 to 0.8. However, this value can change based on specific conditions and test methods used.
What is the effect of decreasing the surface area of the block in contact with the table on the coefficient of kinetic friction?
Decreasing the surface area in contact with the table will increase the pressure at that contact point. This can lead to an increase in the coefficient of kinetic friction, as the roughness at the microscopic level can become more significant.
What is the first law of motion to the motion of an ice skater sliding across the ice st a constant velocity?
The first law of motion, also known as the law of inertia, states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by an external force. In the case of an ice skater sliding across the ice at a constant velocity, the skater will continue moving at that constant velocity unless a force (like friction or wind resistance) acts to change their motion.
Why does velocity of water change with depth?
The velocity of water changes with depth due to variations in pressure and friction. Near the surface, water velocity is typically faster due to less friction, while deeper in the water column, velocity may decrease due to increased pressure from the weight of the water above. This change in velocity with depth is also influenced by factors such as the slope of the river or ocean floor and the density of the water.
Is friction the rate of change in velocity?
Acceleration is the rate of change in velocity. It has nothing to do with friction, unless friction is causing the change.
How would the velocity of the book change if the applied force were equal to the sliding friction force?
If the applied force were equal to the sliding friction force, the book would move at a constant velocity since the two forces would be balanced. This means there would be no acceleration or deceleration, and the book's velocity would remain unchanged as long as the forces stayed in equilibrium.
What are substances that change sliding friction to fluid friction?
The materials that, in general, change sliding friction to fluid friction are called lubricants. This class of materials includes oil, grease and the like.
Can you stop friction?
You can reduce it to a point it is not noticeable but can not eliminate it altogether. You can reduce friction through use of materials with lower coefficient of friction like PTFE or by changing the way the materials contact, say change a sliding one to a rotating one.
How the coefficient of friction between a body and a surface change if the mass of the body is doubled?
The coefficient of friction between a body and a surface does not change if the mass of the body is doubled. The coefficient of friction is a property of the material of the surfaces in contact and their interaction, not the mass of the body.
What can change the force of friction?
Changes in the normal force and coefficient of friction you are welcome!!!
How is friction a force?
Due to friction velocity of a body gets reduced, reduction in velocity causes change in velocity. This change in velocity leads to production of acceleration.(Because only acceleration can produce change in velocity either its direction or its magnitiude). And only a force can cause the acceleration hence friction is a force.

If normal force is dobledwhat happens to friction?
Frictional force gets doubled. But coefficient of friction does not change
Which of these is the rate of change in velocity momentum speed friction or acceleration?
The rate of change in velocity is called acceleration.
What happens to coefficient of friction when weight of body is doubled?
If the weight of a body is doubled, the coefficient of friction does not change. The coefficient of friction is a constant for a given pair of materials and surfaces, and it does not depend on the weight of the body.
