Key Terms<\/span><\/h3>\r\n
\r\n \t
banked curve<\/strong><\/dt>\r\n \t
curve in a road that is sloping in a manner that helps a vehicle negotiate the curve<\/dd>\r\n<\/dl>\r\n
\r\n \t
centripetal force<\/strong><\/dt>\r\n \t
any net force causing uniform circular motion<\/dd>\r\n<\/dl>\r\n
\r\n \t
Coriolis force<\/strong><\/dt>\r\n \t
inertial force causing the apparent deflection of moving objects when viewed in a rotating frame of reference<\/dd>\r\n<\/dl>\r\n
\r\n \t
drag force<\/strong><\/dt>\r\n \t
force that always opposes the motion of an object in a fluid; unlike simple friction, the drag force is proportional to some function of the velocity of the object in that fluid<\/dd>\r\n<\/dl>\r\n
\r\n \t
friction<\/strong><\/dt>\r\n \t
force that opposes relative motion or attempts at motion between systems in contact<\/dd>\r\n<\/dl>\r\n
\r\n \t
ideal banking<\/strong><\/dt>\r\n \t
sloping of a curve in a road, where the angle of the slope allows the vehicle to negotiate the curve at a certain speed without the aid of friction between the tires and the road; the net external force on the vehicle equals the horizontal centripetal force in the absence of friction<\/dd>\r\n<\/dl>\r\n
\r\n \t
inertial force<\/strong><\/dt>\r\n \t
force that has no physical origin<\/dd>\r\n<\/dl>\r\n
\r\n \t
kinetic friction<\/strong><\/dt>\r\n \t
force that opposes the motion of two systems that are in contact and moving relative to each other<\/dd>\r\n<\/dl>\r\n
\r\n \t
noninertial frame of reference<\/strong><\/dt>\r\n \t
accelerated frame of reference<\/dd>\r\n<\/dl>\r\n
\r\n \t
static friction<\/strong><\/dt>\r\n \t
force that opposes the motion of two systems that are in contact and are not moving relative to each other<\/dd>\r\n<\/dl>\r\n
\r\n \t
terminal velocity<\/strong><\/dt>\r\n \t
constant velocity achieved by a falling object, which occurs when the weight of the object is balanced by the upward drag force<\/dd>\r\n<\/dl>\r\n<\/div>\r\n \r\n\r\n<\/div>\r\n
