Terminology for Week 4

Arc pg. 396

the portion of the graph of a continuous differentiable function f on the interval [a,b] that lies between x=a and x=b

Surface of a Revolution pg. 399

the surface that is generated when the arc of a graph is revolved about a line L

Force pg. 404

that which in any way changes the state of motion of a body

Hooke's Law pg. 405

when a spring is pulled x units past its equilibrium position, there is a restoring force F(x)=kx that pulls the spring back to equilibrium

Equivalent Resistance University Physics pg. 833

The equivalent resistance of any number of resistors in series equals the sum of their individual resistances. For any number of resistors in parallel, the recipricol of the equivalent resistance equals the sum of the recipricols of their individual resistances.

Kirchoff's Rules University Physics pg. 837

Junction Rule

the algebraic sum of the currents into any junction is zero

Loop Rule

the algebraic sum of the potential differences in any loop must equal zero

Shunt Resistor University Physics pg. 843

a parallel resistor that can be attached to an ammeter to bypass some of the current and therefore allow the meter to measure currents than its full-scale reading

Potentiometer University Physics pg. 845

an instrument that can be used to measure the emf of a source without drawing any current from the source

Solenoid University Physics pg. 885

a helical winding of wire such as a coil wound on a circular cylinder

Ampere University Physics pg. 801

One ampere is that unvarying current which, if present in each of two parallel conductors of infinite length and one meter apart in empty space, causes each conductor to experience a force of exactly 2x10^-7 newtons per meter of length
