Chapter 5.2-Friction

Questão	Responda
Kinetic Friction	It is exerted on one surface by another when the two surfaces rub against each other because one or both of them are moving.
Static Friction	The force exerted on one surface by another when there is no motion between the two surfaces.
Kinetic Friction Force	\[F^f\]=\[\mu\]x\[F_N\]
Static Friction Force	\[F^f\]<=\[\mu_s\]x\[F_N\]
Coefficient of Static Friction	Between two surfaces and is signified by \[\mu_s\]x\[F_N\] which is the maximum static friction force that must be overcome before motion can begin.
Coefficient of Kinetic Friction	Relates the frictional force to the normal force. \[\mu_k\]
The frictional force is ____________ to the force pushing the surface together.	Proportional
