By my understanding, this is due to the fact that it is easier to keep a moving object in motion than it is to accelerate it from a resting position. When a force is exerted on a stationary object, acceleration relies on that force alone. However, with a moving body, the momentum of the object reduces the force needed to overcome 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.
True -It's "False"!
False. The force needed to overcome static friction is usually greater than the force needed to overcome kinetic friction.
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.
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.
no limiting friction is not less than rolling friction
there is more surface area contact with kinetic friction as opposed to sliding 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.
Sliding Kinetic Friction is usually greater than Rolling Kinetic Friction. Sliding Kinetic Friction is caused by two objects being dragged together, providing more opportunity for the objects' microscopic hills and valleys to catch.
Friction generated between two dry surfaces in contact during motion. Kinetic frictionis a product of the coefficient of kinetic friction and the normal reaction force. It assumes a constant value regardless of the amount of applied force or the speed of the motion. Its value is always less than the limiting friction between the same two surfaces.

True -It's "False"!
No, static friction is generally stronger than kinetic friction.
False. The force needed to overcome static friction is usually greater than the force needed to overcome kinetic friction.
Limiting friction is just the maximum static friction force (if you go over that point static friction becomes kinetic friction).Let f = frictional force,c = coefficient of frictionN = Normal forcefmax = cN = limiting frictionAlthough the term coefficient of limiting friction is not really used, I'd assume it would just be "c" (it's a coefficient after all). So they would be the same.If you meant is coefficient of friction the same as limiting friction, than the answer is no. Coefficient of friction is just the "c" in the equation. Limiting friction however is the product of the coefficient and the normal force.
