Assuming that all the energy dissipated by kinetic friction goes into melting a small mass m of the ice, and that the rest of the ice block remains at -1.5°C, determine the value of m.

What is the force that keeps you from sliding on an icy sidewalk kinetic friction static friction?
coefficient kinetic
What is the formula for the coefficient of kinetic friction?
Ukn
Which coefficient of friction is greater static or kinetic?
static usully greater then kinetic
What is the coefficient of kinetic energy?
The coefficient of kinetic energy is a constant for friction acting as a retarding or dissipative force to calculate the total force on the object. The coefficient of friction u is represented in equation by the relation F = u*N, where N is the normal force.
Why the coefficient of static friction is greater thant the coefficient of kinetic friction?
When objects are at rest on each other (i.e. static friction) their microscopic irregularities can settle into each other - and can also form electrostatic bonds.
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.
What is the coefficient of kinetic friction between the 13.0kg wooden crate and the horizontal force of 31N of the floor?

What is the coefficient of kinetic friction between aluminun and felt?
The coefficient of kinetic friction between wool felt and aluminum is about 0.24 to 0.26.

A horizontal force of 40 newtons will just start a 600 newton empty sled moving across packed snow what is the coefficients of static and kinetic friction?
static friction= normal contact force*coefficient of static friction 40 = (600*9.8) * CSF CSF=40/(600*9.8) (you can calculate that yourself, i cant be bothered) there isn't enough info to work out the coefficient of kinetic friction
What is coeffitient of stactic n kinetic friction?
The coefficient of static or kinetic friction depends on the surfaces that are causing friction. The formula for it is: force of friction over normal force.
What is the coefficient of kinetic friction between aluminum and cork?
0.35, approximately
What is the coefficient of kinetic energy?
The coefficient of kinetic energy is a constant for friction acting as a retarding or dissipative force to calculate the total force on the object. The coefficient of friction u is represented in equation by the relation F = u*N, where N is the normal force.
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
When the block of mass is increased is there an increase in the value of coefficient of kinetic friction?
No, coefficient of friction is dependent on the materials in contact, not their mass. However the FORCE of friction will increase as the mass increases in this case.
