activated

Set in motion

Activated describes something that has been made active or set in motion.

A device is activated when turned on or triggered: The alarm was activated by motion sensors.

In science, activated substances have been treated to increase reactivity: activated charcoal, activated carbon.

In casual use, activated often describes someone energized or ready for action: I'm fully activated after that coffee.
