# Inclined Plane Friction: Independent of Mass?

• Jandaberg123
So as long as the coefficient stays the same, friction will be independent of the mass.In summary, friction on an inclined plane depends on the force applied normal to the surface, which is mgcos(alpha). This means that the friction coefficient is independent of the mass, as long as it remains constant. Therefore, the statement on YouTube that Ffmax is mgcos alpha is correct.

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.
