Here's why:

* Electric Force: Electric force is a fundamental force in physics that arises from the interaction of charged objects. It's what causes electrons to move in response to the presence of other charged particles.

* Newton: The Newton is the standard unit of force in the International System of Units (SI). It's defined as the force needed to accelerate a 1 kilogram mass at a rate of 1 meter per second squared.

While the movement of electrons is related to electric force, it's important to note that the force itself isn't directly measured in units related to electron movement. Concepts like electric current (Amperes) or electron drift velocity are used to quantify the flow of electrons.
