Understanding Friction and Normal Force on Inclined Planes

AI Thread Summary
The normal force acts perpendicular to the surface of an inclined plane, while the frictional force opposes the motion due to gravity along the plane. The maximum frictional force is determined by multiplying the normal force by the coefficient of static friction. It is incorrect to equate the normal force with the frictional force, as friction is typically a fraction of the normal force's magnitude. For instance, with a friction coefficient of 0.5, the frictional force equals 0.5 times the normal force. Even on a frictionless surface, the normal force exists, but there is no frictional force acting.

can i say normal force acting on the object perpendicular to the surface is the frictional force??
because if the normal force is great enough, the object will not slide down...so, can i say frictional force is normal force?

help me...thank you

Friction force would be opposing gravity, in the direction of the inclined plane's surface. The normal force perpendicular to the plane times the coefficient of static friction determines the maximum frictional force before sliding occurs.
 
no, you cannot say that the normal force is the frictional force...typically, the frictional force is , say, a percentage of such force's magnitude...

for example, if a surface has a 0.5 friction coefficient, then the frictional force is 0.5xnormal_force

then again, if you are on a surface with zero friction coefficient, the normal force is still there, but there is no friction.
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
