Would an object take longer to fall than the other in these circumstances? the two objects have the same mass and initial velocity, but the first object is physically larger than the second one? could you explain why?

No they are falling the same distance and the weight doesn't matter. Neither does the mass and matter. It just depends on the height in which they are falling at the same amount of time.

Hoped I helped!

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.

True will be your answer dude
