Sliding friction is shown in hockey when you hit the puck. The puck has friction against the ice (but there isn't much).

Is there objects that do not have friction?
No, all matter contains friction and is shown when in contact with other matter. A molecule of ice has friction, though it may take the tiny thing a few years to have any affect upon something.
Does the earths magnetic field has periodically reversed direction?
Yes. In historical times , clay pots have shown that the earth's magnetic field has reversed.
What are microwelds?
Table of CoefficientsThe coefficient of kinetic friction is always less than or equal to that of static friction.The table below shows many coefficients of friction. Notice that each value is always given for a pair of surfaces. Friction doesn't work unless there are two surfaces.Also note that there are values shown for both static friction and kinetic friction. Static friction deals with starting to move something, while kinetic friction deals with keeping something moving once it's already in motion.In each case, it's also important to note that the coefficients of kinetic friction are always less than or equal to the coefficients of static friction. objectWrite('');Coefficients of Friction for Pairs of SurfacesSurfaces in ContactCoefficient of Static Friction (s)Coefficient of Kinetic Friction (k)Wood on wood0.50.3Waxed ski on snow0.10.05Ice on ice0.10.03Rubber on concrete (dry)1.00.8Rubber on concrete (wet)0.70.5Glass on glass0.940.4Steel on aluminum0.610.47Steel on steel (dry)0.70.6Steel on steel (lubricated)0.120.07Teflon on steel0.040.04Teflon on Teflon0.040.04
What cause friction?
The causes of the resistive force of friction are1.molecular adhesion2.surface roughness3.the plowing effect.Adhesion is the molecular force resulting when two materials are brought into close contact with each other. Trying to slide objects against each other requires breaking these adhesive bonds. For years, scientists thought that friction was caused by surface roughness, but recent studies have shown that it is actually a result of adhesive forces between the materials.But surface roughness is a factor when the materials are rough enough to cause serious abrasion. This is called the sandpaper effect.When one or more of the materials is relatively soft, much of the resistance to movement is caused by deformations of the objects or by a plowing effect.
Explain why physics is considered a basic science?
Physics can be considered to derive from mathematics and is the study of both matter and energy. It is considered to the basic science, because all other sciences can be shown to be derived from it. Any field or science has some amount of physics with in it.
What kind of friction shown in a pushed chair?
Escherichia coli , salmonella, Staphylococcus
The coefficient of friction between the wall and the 6 kilograms block shown is 0.2 what force will keep the block sliding up uniformly?
I see no diagram. Are you asking what HORIZONTAL force will keep the block from sliding up ? Where is the Diagram?????
Is live hockey going to be shown on 215?
No it is not I am very sorry dude.
What are the difference between elactric field and electric displacement field?
The electric displacement field is a vector field, shown as D in equations and is equivalent to flux density. The electric field is shown as E in physics equations.
Why is there more national pride shown in hockey than in other major sports?
The countries that show such pride are typically the stronger teams, and often those with long histories in the sport. Canada and the northern European countries are normally quite fierce in competition ice hockey, where the central European, south/middle Asian and Australasian countries are very supportive of their teams in field hockey.

Why doesn't the fattest man in the world become a hockey goalie?
The fattest man in the world cannot be a hockey goalie because the position requires flexibility, which cannot be shown by such a fat person.
Does field exist between lines?
Yes, usually. The lines are simply shown to illustrate direction and strength of the field.
What is the difference between static friction and limiting static friction?
When two bodies that are not moving relative to each other are in contact, the friction force acting between their surfaces is known as static friction or limiting friction. This friction force will prevent one of the bodies from moving over the other, or sliding down a slopped surface, except an applied force is greater than it.Static friction Fs, also known as limiting friction, is the maximum friction force that is produced and which must be overcome for a body to move over, or slide down the surface of another body.Laboratory experiment to demonstrate static friction: experiments can be carried out in the lab to show the presence of static friction on the surfaces of two unmoving bodies as follows:Consider a body A on a plane surface, and a force is gradually and increasingly applied on it using a spring balance, as shown in the figure below.At any instant, the friction force F between the surfaces adjusts itself to be equal and opposite to P, so that the body is in equilibrium.As the force P is gradually increased, a point is reached when the body A is just about to move. The body is said to be in limiting equilibrium at this stage, and the value of P, which is noted by the spring balance represents the value of the maximum frictional force, which is also known as the static or limiting friction, Fs that is acting on the surfaces.If P is increased further, beyond the static or limiting friction, the body begins to move with steady speed. The frictional force now acting is known as Kinetic Friction, also known as Sliding or Dynamic Friction, Fd. Dynamic friction is usually found to be less than static friction.A good example of the action of static friction is at the contact between a car's tire and the ground. Even when the car is in motion, the section of the tire in contact with the ground is not actually moving (it is the wheel that is moving) relative to the ground, therefore static friction is present, and enables the car's wheel to roll on the ground without losing balance.
Does the earths magnetic field has periodically reversed direction?
Yes. In historical times , clay pots have shown that the earth's magnetic field has reversed.
Which sports are shown on the Setanta network besides soccer?
Setanta offers a variet of sports to its subscibers. Gaelic football, Australian rules football, hurling, cricket, golf, boxing and ice hockey are all regularly shown.
Was a Civil War battle fought at St Davids Field TN?
No, neither the field, battle, nor the generals shown are real - it is all a fiction...
