What else can I help you with?
Is rolling friction greater than sliding friction?
Typically not. However rolling friction is somewhat of a myth. Rolling friction is actually caused by static friction. There are really only two types of friction: Static and Kinetic. That's it! Rolling friction is caused by static friction and the coefficient of friction (which determines its strength) is dependent upon the two materials of interaction.
When and object slides over a smooth horizontal surface how does the force of friction depend on the force of gravity on the object?
If the surface is smooth then it is almost frictionless. Hence the body will continue to move with constant velocity. However the object continues in a circular path and the weight is thus the centripetal force. It is assumed that the surface is very large)
What direction does the force of friction act when a body slides?
In the direction opposite to that of the sliding body.
How can an adjustable inclined plane be used to measure the coefficient of static friction and coefficient of kinetic friction?
Place the object on the plane. Slowly increase the angle of the plane until the object begins to move at angle Θ. The µs = tan Θ. For µk, same process, but give the object a little push at each increasing value of Θ.
When two continental plates collide sometimes one plate slides beneath the other in a process known as subduction. When one continental plate slides beneath another......?
material from the Earth's surface is returned to the interior.
What is kinetic friction and sliding friction?
Kinetic friction is the friction that arises between surfaces in relative motion. Sliding friction is the friction that occurs when an object slides over a surface.
What friction slows down an object that slides?
The force of kinetic friction acts in the opposite direction to the motion of the object, slowing it down as it slides. This friction is caused by the interaction between the surfaces of the object and the surface it is sliding on. It is proportional to the normal force between the surfaces and the coefficient of kinetic friction.
Which form of friction is the one that deals with objects that are already moving?
Kinetic friction is the form of friction that deals with objects that are already in motion. Kinetic friction opposes the motion of an object as it slides or moves across a surface.
When an object over a surface the kind of friction that occurs is called friction?
false
What Type of friction is present on a water slide?
The type of friction present on a water slide is kinetic friction. Kinetic friction occurs when an object moves across the surface of another object, in this case, when a person slides down the water slide. The water on the slide reduces friction, allowing the person to slide more easily.
What are the three types of friction and when does each apply?
There are three types of friction, static friction, rolling friction, and sliding friction. Static friction is friction between two surfaces that aren't moving relatively to each other. Rolling friction is friction between a rolling object and the surface that it is rolling on. Sliding friction is friction where an object slides, or rubs against, another surface.
When solids surface slides over each other the kind of friction that occurs is called BLANK friction?
When solids surfaces slide over each other, the type of friction that occurs is called kinetic friction. This type of friction opposes the motion of the objects relative to each other, causing resistance.
A 5.0 kg block of ice at -1.5C slides on a horizontal surface with a coefficient of kinetic friction equal to 0.058 The initial speed of the block is 6.0 ms and its final speed is 5.5 ms.?
Assuming that all the energy dissipated by kinetic friction goes into melting a small mass m of the ice, and that the rest of the ice block remains at -1.5°C, determine the value of m.
When a body slides or rolls over the other body the force of friction is said to be?
When a body slides or rolls over another body, the force of friction is called kinetic friction. This friction arises due to the contact between the surfaces of the two bodies and opposes the relative motion between them.
When an object roll over a surface the kind of friction that occurs is called friction?
When an object rolls over a surface, the friction that occurs is called rolling friction. Rolling friction is lower than sliding friction, which occurs when an object slides along a surface. Rolling friction results from the deformation of the object and the surface it is rolling on.
Thermal energy is produced when firefighter slides down a pole where does it come from?
The potential energy (due to the fighter's position in the Earth's gravity field). This is converted into kinetic energy as the fighter begins the slide and this kinetic energy is turned into heat energy by friction as the fighter slides.
What factor does the limiting value of the force of the static friction depend?
limiting friction is force of friction when a body slides over the surface of another body
