Which action is associated with the starter motor?

The action associated with the starter motor is engaging and rotating the engine flywheel. The starter motor is a crucial component of the vehicle's starting system, which is responsible for initiating the engine's operation. When you turn the ignition key or push the start button, the electrical energy from the battery energizes the starter motor. This motor then engages with the flywheel, which is part of the engine's crankshaft assembly.

Once engaged, the starter motor spins the flywheel, which in turn rotates the crankshaft of the engine. This rotation is necessary for the engine to begin the combustion process. Without the starter motor's ability to engage and rotate the flywheel, the engine would not start, as the compression and ignition cycles required to start the engine would not occur. Thus, the primary function of the starter motor revolves around this essential task of engaging with the engine's flywheel during the starting phase.
