| 11. | For most surface interfaces, the coefficient of kinetic friction is less than the coefficient of static friction.
|
| 12. | Static friction is friction between two or more solid objects that are not moving relative to each other.
|
| 13. | :: Your power steering pump is incorrectly producing more static friction of tires when you're stopped.
|
| 14. | Also, to even calculate either rolling resistance or static friction, one needs a weight for the car.
|
| 15. | The coefficient of static friction is a derived number, dependent on the limiting friction and the normal force.
|
| 16. | By balancing forces, you can calculate the frictional force required and therefore the minimum necessary coefficient of static friction.
|
| 17. | The molecules of the surface exhibit a net positive force against the molecules of the sledge-- static friction.
|
| 18. | Typically, the static friction coefficient ( a heuristic number ) between two surfaces is larger than the kinetic friction coefficient.
|
| 19. | A point is reached at which string tension is great enough to overcome the static friction between the string and bow.
|
| 20. | This angle is equal to the arctangent of the coefficient of static friction " ? " s between the surfaces.
