This set covers Abeka Physics Chapter 10: "Circular and Periodic Motion" (pages 144-157).
Terms in this set (18)
periodic motion
term for any motion that occurs repeatedly after the same lapse of time
uniform circular motion
type of motion that an object exhibits when it follows a circular path at constant speed
centripetal acceleration
term for an orbiting (or rotating) object's acceleration
toward
the center of a circle due to a force causing a constant change in direction
centripetal force
term for any force producing centripetal acceleration
centrifugal force
term for any force that pushes or pulls an object
away
from the center of a circle
equilibrium
point at which the restorative force on an object and its original force are in balance
oscillatory motion
term for repetitive motion back and forth over the same path
period
term for the time it takes for one full oscillation to occur
amplitude
term for the absolute value of the maximum displacement in either direction during oscillation
frequency
term for the number of oscillations that occur per unit time
simple harmonic motion
term for periodic motion that follows the same path over the same time interval and is caused by a restorative force that is proportional to displacement
simple pendulum
term for a freely swinging mass hanging from a thin, massless connector
the square root of its length

physical pendulum
term for any rigid body mounted so that it can swing in a plane about a point of support
