Does an object move when its under maximum static friction?

OpenStudy (anonymous):

no as it start moving kinetic friction comes into play:)

OpenStudy (anonymous):

No, It doesn't

OpenStudy (anonymous):

so if it doesn't what would you give as the answer for the minimum force need to move the object?

OpenStudy (anonymous):

the maximum static frictional force occurs when object starts moving...

OpenStudy (anonymous):

F=u(kinetic friction)*N(normal reaction) if you decrease the normal reaction any how as u remains constant so force can be minimized:)

OpenStudy (anonymous):

@gerryliyana he is asking for minimum force nt for minimum coefficient:)

OpenStudy (anonymous):

F minimum = f static frictional max

OpenStudy (anonymous):

Thank all of you. I was asking if say the maximum friction is 20N so how much force must be used to overcome friction(no without changing normal reaction)

OpenStudy (anonymous):

do you mean maximum static friction? or kinetic friction??

OpenStudy (anonymous):

if Force = maximum static friction, so object starts moving if Force > maximum static friction, so object is moving

OpenStudy (anonymous):

ah thank you very much

ur welcome
