You move from location i at < 4, 4, 4 > m to location f at < 5, 6, 7 > m. All along this path there is a nearly uniform electric field < 1000, 190, -490 > N/C. Calculate , including sign and units

As newton's first law states a object in motion stays in motion

Sound energy is produced when an object vibrates. examples are 1- a balloon popping2-a whistle3- a waterfall

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
