What is friction dependent on?
Answer: Friction is a resistive force, which comes into play when there is a relative motion between two bodies in contact. The frictional force between two bodies depends mainly on three factors: (I) the adhesion between body surfaces (ii) roughness of the surface (iii) deformation of bodies.
What does kinetic friction depend on?
Kinetic friction is sometimes referred to as sliding friction. Both static and kinetic friction depend on the surfaces of the box and the floor, and on how hard the box and floor are pressed together.
Which depends on the frictional force answer?
The magnitude of the frictional force depends on the weight of the object and roughness of the surface in contact.
Which depends on the friction force?
2) The force of friction depends on the nature of the two surfaces in contact. 3) The force of friction is independent of the area of the two surfaces in contact. 4) For the two surfaces, the limiting frictional force is directly proportional to the normal reaction.
Does static friction depend on material?
It is a ratio of the force of friction between two bodies and the force pressing them together. For a given pair of surfaces, the coefficient of static friction is larger than the kinetic friction. The coefficient of friction depends on the materials used.
Does friction depend on velocity?
Friction does depend on the sliding velocity, but this de- pendence is far from universal: some measurements find an increase when velocity increases, while others find a decay [8–10] or even a more complex non-monotonous behavior [2].
Does friction depend on contact area?
It does not depend the area of contact, it doesn’t depend on the sliding speed. Next, there will probably be some type of friction laboratory experiment. In this lab, students will measure coefficients of friction and show that the frictional force doesn’t depend on surface area in contact.
What are the two factors on which force of friction depends?
The two factors that determine the strength of the force of friction between two sliding objects are the mass of the object, coefficient of friction.
What are the main factors on which friction depends?
Roughness/smoothness of the sliding object
What does friction allow us to do?
Friction is the resistance to motion of two objects held against each other. Friction that allows us to walk depends on gravity to convert our mass to weight which holds our feet against the surface where static friction enables the soles of our shoes to push off against the surface of the Earth.
What does friction always do to an object?
Friction always works in the direction opposite to the direction in which the object is moving, or trying to move. Friction always slows a moving object down. The amount of friction depends on the materials from which the two surfaces are made.
What does it mean to “overcome” friction?
It means the work done to overcome friction. As you must be knowing, friction is always present, and some work has to be done to start motion or to keep the motion uniform. That very work done is termed as “wirk done against friction”. Jan 6, 2019.
