What is limiting value of friction?
The maximum friction that can be generated between two static surfaces in contact with each other. Once a force applied to the two surfaces exceeds the limiting friction, motion will occur. For two dry surfaces, the limiting friction is a product of the normal reaction force and the coefficient of limiting friction.
Examples of force of friction that causes an object to accelerate?
Once a particular reference frame is established, whenever friction is observed between two objects, one of the objects speeds up as a result of the frictional force and one of the objects slows down with respect to that reference frame. Imagine a wooden block at rest on an ideal, frictionless surface. If you were to place something on top of the block and drag it across the surface of the block, the friction that resulted would cause the block to move. Since it started at rest and it ended in motion, it sped up as a result of a frictional force. In this example, since the non-frictional forces (the weight of the something you dragged along the top surface of the block) can only be exerted in the direction of the normal, the only force that is left that could possibly cause any movement of the block is due to friction.
What does the y - intercept on a force vs acceleration graph represent?
Answer #1:The y intercept should be zero because of Newton's second law. Force andacceleration are directly proportional. The X intercept indicates that there issome force required to overcome friction if friction is not negligible. This valueis the force required to accelerate the object usually very small.===============================Answer #2:It's even easier than that. The graph had better pass through the origin,because zero force on an object means it can't be accelerating, and zeroacceleration of an object means there can't be any net force acting on it.Go back and read Answer #1 above very carefully. It correctly says that they-intercept is zero. But doesn't that mean that the graph must go through theorigin, and that the x-intercept is therefore also zero ? I'm just sayin . . .
Factors affecting movement?
Three factors that affect movement are friction, wind resistance, and velocity. Friction is the resistance that a single object encounters when moving over another object. Velocity is speed, and wind resistance is the opposing force on an object.
What will be the direction of friction on a accelerating car by the road?
For a car accelerating on the road, the direction of friction will be the same as of the car.
What are four forces in static friction?
Four forces in static friction are:- 1. Weight 2. Tension 3. Normal Force 4. Static Friction
Is there a formula for friction?
simple one is: max friction = coefficient of static friction*normal force
What is the equation for static friction?
Fs=mu*FNFs=Static Friction mu=coefficient of static friction FN=Normal force
What relationship exists between the static frictional force and the normal force on an object?
Normal Force is the Gradient of the Gravitational Scalar Energy,Normal Force = - Del GmM/r.Gravitational Force is GmM/r^2 and is a Scalar force. Normal Force is RGmM/r^3 where R is the radial vector.
Describe the factors that cause static friction between two surfaces to increase.?
A higher coefficient of static friction increases the static frictional force. A greater normal force also does this.
What is coeffitient of stactic n kinetic friction?
The coefficient of static or kinetic friction depends on the surfaces that are causing friction. The formula for it is: force of friction over normal force.
What does the coefficient of static friction represent?
In free space or on a frictionless surface, it takes no force to move something. Where there is friction, the ratio of (force necessary to start it moving horizontally)/(the object's weight) is the coefficient of static friction on the horizontal surface.
What happen to the static friction force as the mass is increased?
It increases. Static friction is the friction that opposes an object at rest to begin moving, given the following formula :- Fs = MsN, where ms is the coefficient of static friction, and n is the normal force, which is equal to mg if is at the x-axis. As the formula shows, the static friction increases with an increase in mass.
What is the relationship of the starting friction to the static friction between two objects?
When an object is at rest on a particular surface, the frictional force keeping it from sliding in any given direction is known as static friction; the magnitude of this force is always less than or equal to the product of those surfaces' static friction coefficient and the component of the gravitational force (weight) of the object perpendicular to the plane of the surface, the latter of which is equal to the normal force that is exerted by the intermolecular bonds in the surface material, upward and perpendicular to the plane of the surface itself. (In other words, Fs ≤ µsFn, where Fs=force of static friction, µs=static friction coefficient, Fn=normal force of surface upon object.)
When is static friction applied?
Static friction is not necessarily an applied force, but something that occurs when there is an applied force. Static friction occurs when there is no motion and there is a force being applied to an object on a surface.
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.
