1. An electronic apparatus comprising:
a container;
a sensor;
a driving unit; and
a processor configured to:
based on sensing data received through the sensor, measure, at a predetermined time interval, external forces exerted on the electronic apparatus from a ground on which the electronic apparatus is located,
identify, based on frequency characteristics of the external forces and a natural vibration frequency of a liquid contained in the container, a frequency having frequency characteristics corresponding to the natural vibration frequency among frequencies of the external forces, and
input a driving signal to the driving unit, based on a size of the identified frequency, the driving signal controlling a velocity of the electronic apparatus according to a natural vibration period of the liquid.
