Make sentence

Amplitude          is                 the           maximum         displacement                   of                        a         particle              from                   its                      equilibrium               position

Forced            oscillation            is            an              oscillation         caused             by

an             external             driving            force;            the           frequency              is

determined              by             the            driving               force,             and             is

not             the             natural               frequency          of          the                 oscillator

Free         oscillation         is     an            oscillation             at            is            the       

natural                frequency              of            the             oscillator

Natural              frequency             is          the           unforced          frequency     of

oscillation           of            a              freely             oscillating               object.

Oscillation             is              a           repetitive              back          -and             -forth

Or           up-          and            -down             motion

True or false

Amplitude the maximum distance  of a particle from its initial position

Forced oscillation is an oscillation caused without external driving force; the frequency is determined by the driving force, and is the natural frequency of the oscillator

Free oscillation is an oscillation at is not the natural frequency of the oscillator

Natural frequency. The forced frequency of oscillation of a freely oscillating object.

Oscillation is a repetitive back-and-forth or up-and-down motion
