As the hang glider and pilot move through the air, they collide with air molecules. The frictional force caused by these collisions is known as drag, which slows the glider down. The amount of drag is proportional to the airspeed of the hang glider: The faster the glider moves, the more...
As inflation accelerates, workers may supply labor in the short term because of higher wages—leading to a decline in the unemployment rate; however, over the long haul, when workers are fully aware of the loss of their purchasing power in an inflationary environment, their willingness to supply...
It's important to note that labor force measures, such as the unemployment rate, are based on the civilian non-institutional U.S. population ages 16 and older. Labor force measures exclude persons who are below the age of 16, people confined to institutions, such as nursing homes and prison...

What precautions should we take while doing the experiment to understand the nature of friction ? Give an example where friction causes an increase in kinetic energy. There is a limit beyond which further polishing of a surface increases rather than decreases frictional force. Explain. ...
the frictional force FfricFfric; the relative velocity vrelvrel between sample and counter body; the loss of volume due to wear VwVw usually determined by the mass loss assuming constant material density. A tribological test setup needs to be found that provides the ability to derive directly th...
A synchro's purpose is to allow the collar and the gear to make frictional contact before the dog teeth make contact. This lets the collar and the gear synchronize their speeds before the teeth need to engage, like this image. HowStuffWorks The cone on the blue gear fits into the cone-...
Is tension a frictional force? How are impulse and momentum related? Why is tension force an internal force? Explain the relationship between amperage, voltage and power. How is torque related to angular momentum? What is the voltage associated with a 1\times 10^{-3} C charge, 2 meters aw...
Often, this quantity is expressed as ideal mechanical advantage, or IMA, which is the mechanical advantage the machine would enjoy if not frictional forces were present. Lever Basics A simple lever is a solid rod of some sort that is free to pivot about a fixed point called a ...
Cyclical unemploymentis caused by changes in the business cycle, such as recessions. Frictional unemploymentoccurs when workers leave their jobs and take some time to find a new employer. Institutional unemployment occurs as a result of policies that alter the features of the labor market, such as...
