| Question | Answer |
| 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 |
