Question

a) Up until and including the point of the maximum static frictional force. what is the relationship between the opposing forces that you measure?

b) Is it possible to apply a force to an object and still have it move with constant speed (that is not zero)? If so, how is that possible? What forces are involved?:

c) What measurement(s) are similar in the determination of the coefficient of kinetic friction and the coefficient of static friction?:

Answer 1

(a)
Up until and including the point of the maximum static frictional force. what is the relationship between the opposing forces that you measure ?
Max Static Frictional Force = us*Fn
Where us is the coefficient of Static friction and Fn is the normal Force !!

(b)
Is it possible to apply a force to an object and still have it move with constant speed (that is not zero)? If so, how is that possible? What forces are involved?:
Yes it is possible,
When Friction force is acting on the object which neutralises the effect of Force applied !!

(c)
What measurement(s) are similar in the determination of the coefficient of kinetic friction and the coefficient of static friction?:

In both of them we first need to find the Normal Force acting on the object in question, because

Friction Force, Fr = u * Fn
Where u is the coefficient of kinetic/Static friction
Fn is the Normal Force
