RafaFriction is greatest when two surfaces are pressed tightly together with a force perpendicular to the surfaces, creating a larger contact area. This results in stronger intermolecular interactions and resistance to motion. Additionally, friction tends to be higher when the surfaces are rough.

In this section you learned about friction. Answer the question(s) that follow. types of friction has the greatest strength A. static friction B. sliding friction C. rolling friction?
A. Static friction has the greatest strength among the three types of friction—static, sliding, and rolling. Static friction is the force that resists the initiation of sliding motion between two surfaces in contact.
What type of friction has the most friction?
Static friction typically has more friction than kinetic friction. Static friction occurs when an object is not moving, and the friction force is at its maximum to prevent the object from moving. Once the object overcomes static friction and starts moving, the friction force decreases to kinetic friction.
Which would you expect to have the greatest amount of friction?
I would expect a rough surface to have the greatest amount of friction due to the increased contact points between the surfaces, resulting in a higher resistance to motion. Smooth surfaces typically have less friction due to reduced contact points.
What types of surfaces produce the greatest amount of friction?
Rough surfaces typically produce the greatest amount of friction because there are more contact points between the surfaces, leading to increased resistance to motion.Smooth surfaces, on the other hand, tend to have less friction due to reduced contact points and smoother interactions between surfaces.
What is the greatest acceleration that can be generated by a runnerif the coefficent static friction between shoes nd road is 0.95?
The greatest acceleration a runner can generate is limited by the static friction force, which is given by the product of the coefficient of static friction and the normal force. If the coefficient of static friction is 0.95, then the maximum acceleration would be 0.95 times the acceleration due to gravity (9.81 m/s^2), which equals 9.31 m/s^2.
