Want this question answered?
A large book has more mass, which requires more force to be moved.
coefficient of friction = force required to move it / mass 0.8 = f / 300 0.8 * 300 = f 240(slugs) = f
i think it's GLacier...Or it could be you're thinking of an avalanche: it's what happens when a large mass of snow is dislodged from a mountain slope or peak and cascades downward with great speed and force.
B/c the sharp edge is needed to provide control and forward motion. w/o the edge the skates would just as happily slide sideways across the ice which would make controlled skating slow, and close to impossible.
Friction force is equal to the force applied only when the object is not moving or it is just beginning to slide. Once the object has started motion completely, it means that the force applied has exceeded the frictional force

Gravity - and friction. The larger book has more gravity - holding it own onto the desk. Friction stops the book sliding sideways.
you can push is across

The carpet provides more friction
It can slide if there is enough force to overcome static friction. Similarly, it can roll if the force is great enough to impart a sufficiently large turning moment (and maintain it).
Friction i do believe
friction
An unbalance force is one that is not opposed by an equal and opposite force operating directly against the force. Examples of unbalanced force are when you kick a ball, or slide furniture across the floor.
i wish i knew how
FRICTION
