What is the kinetic energy of a penguin with a mass of 8 kg that is running at a speed
of 3 m/s?

mass (m) = 8kg
velocity (v) = 3 m/s²

Ke = ½mv²

ke = ½ mv²
½ × 8 × 3²
½ × 24²
12

U okay bro

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.
