More force is needed to slide a large book across a table than to slide a small book primarily due to the difference in weight and surface area. A larger book typically has a greater mass, resulting in a higher gravitational force acting on it, which increases the friction between the book and the table. Additionally, the larger contact area can contribute to increased friction, requiring more force to overcome it and initiate movement.
A large book has more mass, which requires more force to be moved.
The force needed to slide the wooden block can be calculated using the formula: force = friction coefficient * mass * gravity. Given that the mass is 300 slugs and the friction coefficient is 0.80, the force required will be 2400 lbs.
The force needed to slide the mass at a constant velocity is equal in magnitude and opposite in direction to the frictional force. The frictional force is calculated as the coefficient of friction multiplied by the normal force (frictional force = coefficient of friction * normal force). Hence, the force needed would be 0.43 times the weight of the mass (force = coefficient of friction * mass * gravity).
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.

No large force is needed for a hockey puck to slide across a frictionless surface. Once the puck is in motion, it will continue to move indefinitely without any additional force due to the absence of friction.
Gravity - and friction. The larger book has more gravity - holding it own onto the desk. Friction stops the book sliding sideways.
The force needed to slide the crate at constant velocity is equal in magnitude but opposite in direction to the force of friction. The force of friction can be calculated as the product of the coefficient of friction and the normal force acting on the crate (weight of the crate). Therefore, the force needed would be 250 kg * 9.8 m/s^2 * 0.25 = 612.5 N.
The force that slows you down as you slide across the floor is primarily kinetic friction. This force arises due to the interactions between the surfaces of the sliding object and the floor, leading to resistance that opposes the motion.
you can push is across

The force of friction between the box and the floor. This force opposes the motion of the box and must be overcome by the pushing force to make the box slide.
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).
The force between two surfaces that are sliding or trying to slide across one another is called friction. Friction is a resistive force that acts in the opposite direction to the motion or potential motion of the surfaces in contact.
Friction i do believe
