Q: This force is represented by a first derivative with respect to position in the harmonic oscillator equation. In one model, this force stems from tiny electrostatic repulsions. It can be understood as the parallel shear component of the contact force, whose other component is typically calculated as mg cosine theta. It is calculated from a coefficient, symbolized mu, multiplied by the normal force. Rolling motion is affected by the "kinetic" type of this force, which is known as "drag" in fluids. For 10 points, name this force that resists the motion of objects against one another.

Q: This movement was not put down until Henry le Despenser defeated John Litsters army, long after it had targeted Fleet prison and Savoy palace. Some of its instigators grievances about the Statute of Laborers, but it executed Robert Hales and Simon of Sudbury for administering the one-shilling fee that nominally sparked it. Shortly after it rose out of Essex and Kent to challenge Richard II, its leader was killed in a scuffle with William Walworth, the mayor of London.

Q: One of them requires the pianist to stamp his heel heavily upon the floor during its third and fourth sections, a motif repeated by a later one named Stoptime. Most of them begin with a four-measure octave introduction, and follow an A-B-A-C-D format, although that pattern is broken in late ones named Magnetic and Silver Swan. Collaborators with the main composer of them included Arthur Marshall and Louis Chauvin, and lesser-known ones include The Easy Winners and The Strenuous Life, a tribute to Theodore Roosevelt. The most famous one was the first piece of sheet music to sell over one million copies, and was named for a club in Sedalia. FTP, name this group of compositions which includes Elite Syncopations, The Cascades, The Entertainer, and the Maple Leaf.
