A more thorough explanation:

A Vice President is a person who is selected in advance to fill the position of the President if the President dies, resigns, is removed from office, or cannot or will not serve. In the United States, the Vice President is elected at the same time as the President and serves as the presiding officer of the Senate. If the President is unable to fulfill their duties, the Vice President takes over as the President.

Another meaning of Vice President is a corporate officer of midlevel to high rank who is usually in charge of a department.

For example, if the President of a company is unable to perform their duties, the Vice President takes over as the head of the company. This illustrates the first definition of Vice President.

Another example is the Vice President of the United States, who is currently Kamala Harris. She serves as the presiding officer of the Senate and is next in line to become the President if the current President is unable to fulfill their duties. This also illustrates the first definition of Vice President.
