Homework Statement
Does contact area of the bottom of a shoe affect the friction coefficient?
Also is Static friction affected by mass?
Does Shoe Contact Area or Mass Affect Friction Coefficients?
In summary, static friction is the resistance to motion between two stationary surfaces, while kinetic friction is the resistance to motion between two moving surfaces. The magnitude of static friction is influenced by surface roughness, normal force, and adhesive properties, and is represented by the coefficient of friction. The main difference between static and kinetic friction is their effect on the motion of surfaces.

What is static friction?
Static friction is the force that resists the motion between two surfaces that are in contact with each other and not moving relative to each other.
What is kinetic friction?
Kinetic friction is the force that resists the motion between two surfaces that are in contact with each other and are moving relative to each other.
What factors affect the magnitude of static friction?
The magnitude of static friction is affected by the roughness of the surfaces in contact, the normal force pressing the surfaces together, and any adhesives or interlocking between the surfaces.
How is the coefficient of friction related to static and kinetic friction?
The coefficient of friction is a constant value that represents the level of friction between two surfaces. It is used to calculate the force of static friction and the force of kinetic friction.
What is the difference between static and kinetic friction?
The main difference between static and kinetic friction is that static friction prevents two surfaces from moving relative to each other, while kinetic friction acts to slow down the motion of two surfaces that are already in motion relative to each other.
