  • ¾ With the modern knowledge about the structure of matter we know that electric charges come from elementary particles: negatively charged electron and positively charged proton. In nuclei there are also neutron with no charge. Interaction between charges: two positive charges or two negative charges repel each other. A positive charge and a negative charge attract each other. This interaction is called the static electric interaction.

  • A vector is a quantity that possesses both magnitude and direction. Examples of vector quantities are displacement, velocity, acceleration, and force. A vector quantity can be represented by an arrow drawn to scale. The length of the arrow is proportional to the magnitude of the vector quantity. The direction of the arrow represents the direction of the vector quantity.physics in general is the most scientific study of "physical" and "interaction".
