A. force of static friction: The force of static friction is directly proportional to the mass of the object. This means that as the mass of the object increases, the force of static friction also increases.
B. force of kinetic friction: The force of kinetic friction is also directly proportional to the mass of the object. This means that as the mass of the object increases, the force of kinetic friction also increases.
C. coefficient of static friction: The coefficient of static friction remains constant and does not depend on the mass of the object. It is a property of the surfaces in contact and the roughness of those surfaces.
D. coefficient of kinetic friction: Similar to the coefficient of static friction, the coefficient of kinetic friction also remains constant and does not depend on the mass of the object. It is a property of the surfaces in contact and the roughness of those surfaces.
