Solution
Definition of free vibrations: Free vibration is a type of vibration in which a force is applied once and the structure or part is allowed to vibrate at its natural frequency.
The graph between displacement and time for a body executing free vibrations:
3. Here, +a and -a represent the maximum displacement on both sides i.e., the amplitude of the vibration along with time t.
