Frictional Force Flashcards
1
Q
Frictional force
A
Force that opposes the motion of an object and acts parallel to the surface with which the object is in contact
2
Q
When does static force act on an object
A
While it is still at rest
3
Q
When does an object finally start to move
A
When the magnitude of the applied force exceeds the maximum static friction
4
Q
Kinetic friction is always
A
- constant
- less than maximum friction
5
Q
Kinetic friction formula
A
Fk= uk x Fn
