The coefficient of static friction is higher than the coefficient of kinetic (or sliding) friction because it takes more force to overcome the initial static friction and start an object moving than to keep it moving once it is already in motion. Static friction is present when an object is at rest, while kinetic friction occurs when an object is moving.
What else can I help you with?
Can the coefficient of static friction be equal to the coefficient of kinetic friction?
No, the coefficient of static friction is typically greater than the coefficient of kinetic friction.
Why coefficient of static friction is larger than kinetic friction?
The coefficient of static friction is typically larger than the coefficient of kinetic friction because it represents the maximum force required to start an object in motion, overcoming the initial static friction. Once the object is in motion, the kinetic friction is usually less because the surfaces are already moving relative to each other, resulting in lower resistance.
Which coefficient of friction is greater static or kinetic?
The coefficient of static friction is greater than the coefficient of kinetic friction. Static friction occurs when an object is at rest and must be overcome to start moving, leading to a higher coefficient compared to kinetic friction, which occurs when an object is already in motion.
If the coefficient of static friction is 0.75 what is the coefficient of dynamic friction?
The coefficient of dynamic friction is typically lower than the coefficient of static friction. It can range from 0.3 to 0.6 depending on the materials in contact. Without further information, we can estimate it to be around 0.4 to 0.6 based on common values.
Is it possible for the coefficient of static friction to exceed 1?
Yes, it is possible for the coefficient of static friction to exceed 1. This means that the force required to overcome static friction is greater than the force pressing the surfaces together.

Is the coefficient of dynamic friction greater than the coefficient of static friction and why?
Millions of classroom experiments would indicate that there is, in fact, a difference, but it is most likely caused by dirt, oil, and imperfections on the surfaces. When care is taken to ensure the surfaces are uniform and clean, the difference between static and dynamic friction disappears.
What is the difference between static friction and sliding friction?
Sliding friction is always less than the static friction by small amount.
Why the coefficient of static friction is greater thant the coefficient of kinetic friction?
The coefficient of static friction is typically greater than the coefficient of kinetic friction because it takes more force to overcome the initial resistance to motion (static friction) than to maintain the motion once it has started (kinetic friction). This is due to microscopic irregularities and interlocking between surfaces when at rest, which require a greater force to break compared to when they are already in motion.
Is coefficient of friction or coefficient of limiting friction are same?
No, the coefficient of friction and the coefficient of limiting friction are not the same. The coefficient of friction is a constant value that describes the relationship between the force of friction between two surfaces, while the coefficient of limiting friction specifically refers to the maximum value of friction force that can be exerted before sliding occurs.
Why is kinetic friction less than static friction?
Kinetic friction is typically less than static friction because the surfaces are already in motion when kinetic friction is acting, so less force is needed to overcome the resistance between the surfaces. In contrast, static friction must be overcome to initiate motion, requiring a greater force.
What type of force does low coefficient belong to?
Friction has a low coefficient, usually less than 1.
What is coefficient of friction..?
A higher coefficient of friction indicates that two surfaces in contact have a greater resistence. A lower coefficient of friction indicates that the two surfaces in contact have less resistence. Soccer cleats on grass have a greater coefficient of friction than skates on ice.
