electric filed is vector for sure

speed and direction maybe?

anonymous · Answer

Vectors give magnitude and direction. The direction is important for fields (they are vector fields....they give the magnitude and the direction of the force at any point). The direction is not important for energies (energies are scalars, and only depend on the amount, not the direction). So the only odd one is the electric charge. Ask yourself: Does the charge depend on direction in any way?
