Inclined Plane Friction: Independent of Mass?

AI Thread Summary
Friction on an inclined plane is influenced by the normal force, which is calculated as mgcos(alpha). This means that while the maximum friction force (Ffmax) depends on mass, the coefficient of friction remains independent of mass. The confusion arises from the distinction between the coefficient of friction and the actual frictional force. Thus, while the frictional force increases with mass, the coefficient itself does not. Understanding this difference clarifies the relationship between mass and friction on inclined planes.

I heard somewhere that friction on an inclined plane is independent of the mass of the object. However on youtube, it says Ffmax is mgcos alpha. How is this correct, because it will mean the friction in not independent of the mass of the object.

Thanks a lot.

Friction depends on the force applied normal to the surface. In an inclined plance, this force is mgcos(alpha). Youtube is correct then!

Thanks, I just checked again and realized that the friction COEFFICIENT is independent of the mass, not the friction.
 

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
