restoring force —a force that restores an oscillating object to its equilibrium position
scalar —a quantity that has a magnitude but no direction
series —the arrangement of elements in a circuit so that they are connected in a line, one after the other
time constant —a value related to how long it takes to charge or discharge a capacitor, or for current to
flow in an inductor
torque —the application of a force at some distance from a fulcrum; if the net torque on an object isn’t
zero, the object’s rotational velocity will change
vector —a quantity that has both magnitude and direction
velocity —how fast an object’s displacement changes; equal to the derivative (slope) of an object’s
position–time function
weight —the force due to gravity; equal to the mass of an object times g , the gravitational field
work —the product of the distance an object travels and the components of the force acting on that object
directed parallel to the object’s direction of motion
work-energy theorem —the net work done on an object equals that object’s change in kinetic energy
