Some people think that the coefficient of friction can never be more than 1, but this is not true.

"You can talk about a coefficient of friction and stuff like that," he says.

Under certain conditions, some materials have even lower friction coefficients.

There are certain factors that help determine the value of the friction coefficient.

Which reduced to nothing all the coefficients of mechanical friction.

But I do believe that the oil is their to reduce the dynamic friction coefficient.

Such a surface can have the same friction coefficient as wet ice.

What is the best way for a student to find coefficients of friction experimentally?

Given this imagry, try to figure out what a coefficient of friction is!

The professor was talking about the coefficient of friction.
