most dictionaries/books/apps define this as POWER but it's more like momentum, (a power which is in motion).

Also means to gain steam or lose steam - said of political momentum or the momentum of a trend or ideology.

a large number of people - not in the sense of 'It's crowded today' but like 'There were crowds waiting to greet the Ambassador' - the crowd is united in its purpose.
