Is it true that kinetic friction is always greater than the maximum value of static friction?
Yes, it is generally true that kinetic friction is always greater than the maximum value of static friction.
Is static friction and limiting friction the same?
Limiting friction is the case of static friction where an object is right on the edge of moving, any more force applied to the object will cause it to move. Limiting friction is the largest value that the static friction can take
What is the expression for the maximum value of friction for which the block will not slide down the incline?
The expression for the maximum value of friction for which the block will not slide down the incline is given by the equation: ( ftextmax mus cdot N ), where ( ftextmax ) is the maximum friction force, ( mus ) is the coefficient of static friction, and ( N ) is the normal force acting on the block.
Static friction is a self adjusting force explain?
i think that static friction is the friction onl because of mass and nature of the surface
What is the friction force that acts on an object when it is at rest?
The friction force that acts on an object when it is at rest is called static friction. It is a force that opposes the initiation of sliding motion and prevents the object from moving. The magnitude of static friction is equal to the force applied to the object, up to a certain maximum value.
Is it true that kinetic friction is always greater than the maximum value of static friction?
Yes, it is generally true that kinetic friction is always greater than the maximum value of static friction.
What is the maximum value of static friction?
one
What will happen to the value of friction force when external force acting on the body with mass m is increased from zero to F max such that there is impending motion at F max?
The value of the friction force will increase to match and oppose the external force up to a maximum value known as the static friction force. Once the external force exceeds the maximum static friction force, the object will begin to move, and the friction force will decrease to the kinetic friction force, which is generally lower than the maximum static friction force.

How does the force of friction act relative to an object and motion?
Friction is a force that is created whenever two surfaces move or try to move across each other. -Friction always opposes the motion or attempted motion of one surface across another surface. -Friction is dependent on the texture of both surfaces. -Friction is also dependent on the amount of contact force pushing the two surfaces together normal force. -On the level of surface, the normal force is always equal and opposite to the wieght. -The force of static friction cancels out the applied force right up to and including when static friction reaches its maximum. -For applied forces greater than the maximum force of static friction the block starts to slip and then the value for friction becomes kinetic friction and the box is then under a net force so it accelerates to the right.
How can one determine the value of static friction in a given scenario?
To determine the value of static friction in a given scenario, you can use the equation: static friction coefficient of static friction x normal force. The coefficient of static friction is a constant that depends on the materials in contact, and the normal force is the force exerted perpendicular to the surface. By calculating these values, you can find the static friction force acting in the scenario.
A box of mass 2 kg is set down on a plane inclined 30 degrees from the horizontal The coefficient of static friction is .5 the coefficient of kinetic friction is 0 What is the speed after 3 second?
the maximum value of limiting friction is = coff. of static fric. * normal force. in this case normal force =mgcosA=17N. the coff=0.5 so the maximum friction=0.5*17=8.5N. but the force acting downward on the incline is mgsinA which is =2*10*0.5=10N. as it has breached the value of friction,the block will move.now kinetic fric. will act.As the coff. of kinetic fric.=0,the surface is as good as a frictionless one.use the laws of kinematics to find the velocity(v=u+at,a=gsinA,t=3,u=0) hence the answer is=15m/s. in reality if there is a coff of static fric,ther ewill be a coff.of kinetic fric. good luck. regards carlitos tevez.
Is static friction balanced or unbalanced?
Static friction is a balanced force that acts in the opposite direction of an applied force to prevent relative motion between two surfaces in contact. It reaches its maximum value just before the point when motion is about to occur.
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.
