Give three important “laws” that characterize frictional interactions between two Solids sliding past one another.

Expert Solution & Answer

To determine

The three important “laws” that characterize frictional interactions between two solids sliding past one another.

Answer to Problem 1EA

The three laws of friction are

1. When a body is moving the frictional force is directly proportional to the normal contact force acting on the body.

2. The friction does not depend on the area of contact between the two bodies sliding past one another but depends on the type of surface in contact.

3. The value of coefficient of static friction is slightly more than the coefficient of kinetic friction.

Explanation of Solution

The laws are summarized which will characterize the two solid bodies sliding past each other.

First law:

When a body is moving the frictional force is directly proportional to the normal contact force acting on the body.

Second law:

The friction does not depend on the area of contact between the two bodies sliding past one another but depends on the type of surface in contact.

Third law:

If two solid bodies slide over each other, then the force of friction is given by

fk=μkN

Where, N is the normal contact force and μk is the coefficient of kinetic friction between the surface of the two bodies.

If two solid bodies do not slide over each other then the force of friction is given by

fs≤μsN

Where, N is the normal contact force and μs is the coefficient of static friction between the surface of the two bodies.

Conclusion:

The three laws of friction are

1. When a body is moving the frictional force is directly proportional to the normal contact force acting on the body.

2. The friction does not depend on the area of contact between the two bodies sliding past one another but depends on the type of surface in contact.

3. The value of coefficient of static friction is slightly more than the coefficient of kinetic friction.

4. I've assembled the following assortment of point charges (-4 μC, +6 μC, and +3 μC) into a rectangle, bringing them together from an initial situation where they were all an infinite distance away from each other. Find the electric potential at point "A" (marked by the X) and tell me how much work it would require to bring a +10.0 μC charge to point A if it started an infinite distance away (assume that the other three charges remains fixed). 300 mm -4 UC "A" 0.400 mm +6 UC +3 UC 5. It's Friday night, and you've got big party plans. What will you do? Why, make a capacitor, of course! You use aluminum foil as the plates, and since a standard roll of aluminum foil is 30.5 cm wide you make the plates of your capacitor each 30.5 cm by 30.5 cm. You separate the plates with regular paper, which has a thickness of 0.125 mm and a dielectric constant of 3.7. What is the capacitance of your capacitor? If you connect it to a 12 V battery, how much charge is stored on either plate? =

Learning Goal: To understand the meaning and the basic applications of pV diagrams for an ideal gas. As you know, the parameters of an ideal gas are described by the equation pV = nRT, where p is the pressure of the gas, V is the volume of the gas, n is the number of moles, R is the universal gas constant, and T is the absolute temperature of the gas. It follows that, for a portion of an ideal gas, PV T = constant. One can see that, if the amount of gas remains constant, it is impossible to change just one parameter of the gas: At least one more parameter would also change. For instance, if the pressure of the gas is changed, we can be sure that either the volume or the temperature of the gas (or, maybe, both!) would also change. To explore these changes, it is often convenient to draw a graph showing one parameter as a function of the other. Although there are many choices of axes, the most common one is a plot of pressure as a function of volume: a pV diagram. In this problem, you…
