  • 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

    Every physical object has a _____ ______ of vibration.

    resonance

    term for the point at which the driving frequency and the natural frequency are the same
