Actuate

To cause someone or something to start or to begin moving or functioning; to put into action or operation. This involves triggering a mechanism, initiating a process, or providing the impetus for a change. It often implies the application of force, influence, or a specific stimulus to bring about a desired effect. The term encompasses a wide range of applications, from mechanical systems to human behavior, focusing on the 'how' of initiating a consequence.

Actuate meaning with examples

• The remote control *actuates* the garage door opener, sending a signal to the motor. Once the signal is sent, the electric motor then moves the door's mechanism. This action allows the door to smoothly open or close. Without the remote, the door remains stationary. This specific mechanism directly translates a command into motion, with the remote and its button.
• A sensor detects movement and then *actuates* the sprinkler system. The sensor sends a signal to a control unit, which then opens the valve and releases the water. The water then showers the lawns, keeping the grass green during dry spells. This illustrates how a specific stimulus initiates a functional operation.
• The prospect of a reward *actuated* the employee to work harder. The desire for a promotion and higher salary, or a bonus, motivated the employee to be more productive and to strive toward excellence. In this way, the thought of better things for the individual, motivates the employee's actions on the job. This example shows the word relating to human motivations.
• A sudden loud noise might actuate the animal's flight or defense response. The noise triggers the animal's central nervous system, causing a rapid release of hormones and physical reactions. The animal will go into 'fight or flight' mode. This causes the animal to have a physiological action based on its instinct.
