Friction Flashcards
1
Q
What’s the coefficient of friction
A
Max frictional force before obj moves / reaction force
2
Q
When is the coefficient of friction greater when static or kinetic
A
u static > u kinetic
Bc greater force needed to initiate movement than to comtimue a.already moving thing
3
Q
What does the u change due to
A
Combination of materials
Condition of surfaces
Motion of surfaces
