AC has force through phase shift and by rectification. DC is a force into itself.
You can use a voltmeter to measure dc but you need a special type of movement or a rectifier to measure ac. If you use an oscilloscope for the voltage measurements, the waves are displayed above and below zero. The voltage is only available at any given instant, and could be negative as well as positive. DC is a force that is constant. Like a weight.
