what if there is no friction?

Friction is hte result of Newton's law which says that to any action there is an opposite and equal reaction. Friction is the result of the interlocking of uneven parts of two substances. So you can understand what would happen if there was no reaction to an action. There would be no football, hockey, swimming, baseball, and all other sports.

If there are no gravitational or or frictional forces, then in theory it would travel forever.

You cannot get away from friction.  Material properties are also not going to be exact.

is the ques complete is there any friction between the boxes or any other force. can't understand the ques itself do we have a figure somewhere

If you consider a model in which both surfaces which cause friction have crusts and troughs, and their interlocking causes the frictional resistance, then it is explained as follows.\n\nThe lubricant molecules fill up the troughs in both surfaces and make them more or less even, and hence there is less interlocking among the two surfaces, and so less friction.

at the moment there are the horizontal component of weight and the friction that opposes it are in equilibrium. we must apply a force that with the already present weight compontns will equal the kinetic friction. \nmeaning that \n\nWx + Fp = Friction.\n\n500cos20 + Fp = 0.6*500sin20 =>\n\nfp =367.24N

yes it means that the system is either in equilibrium or no force is being appplied on the point.(i.e. , no charge is present)

Average Kinetic coefficient of friction (m) cannot be calculated as such, \n      since  m can lie anywhere between 0 and 1.\n   \n      Thus, its value is probably more near 0.5 than many values. That's all that can be infered.

If after collision the mass goes to rest i.e. no velocity then momentum is zero.

Frictional force is the force which opposes the relative motion of an object. It is directed opposite to the motion of an object. It is dependent on the coefficient of friction, and on the force applied on the object.\n\nThere are 3 types of frictional forces:\n\n   1. Static friction is the friction acting on a body when the body is not in motion, but when a force is acting on it. Static friction is the same as the force being applied (because the body isn't moving). Static friction acts because the body tends to move when a force is applied on it.\n   2. Limiting friction is the friction on a body just before it starts moving. Generally, limiting friction is the highest.\n   3. Kinetic friction is the friction which acts on the body when the body is moving. Kinetic friction is usually smaller than limiting friction.

the fact is that in the nucleus there is no actual contact between the protons and the neutrons..they are held only by the electrostatic forces.so asolutely no friction

By never-ending it implies that there is no bottom, so you would simply continue to fall for all eternity.  No bottom, no splat, therefore no place to end up.

basically it is the amount of friction, caused by movement, or no movement. below is a GREAT link to explain. hope this helped!!!!\n\nhttp://hyperphysics.phy-astr.gsu.edu/hbase/frict2.html

Yes as long as thing run smooth and there isn't any ripples made.

In the absence of friction, the acceleration of an object down a 12-degree slide would be\n\n9.81 * sin 12, or around 2.04\n\nInstead, your obejct is accelerating at 1.22.\n\nThe loss of acceleration due to friction is\n\n(9.81 * sin 12) - 1.22\n\nand the coefficient of friction is thus\n\n[(9.81 * sin 12) - 1.22] / (9.81 * sin 12)

both.  the friction, as well as creating its own heat, slows the airflow, which aggrivates the compression along the leading edges.\n\nI'm pretty sure.  don't put this on a physics test and then blame me.
