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
