GIVING A ball (mass=0.68 kg) approaches the bottom of the hill, moving at 8.8 m/s. It proceeds to roll up the straight incline (angle of inclination = 3.5 degrees), slowing down at a constant rate of 0.95 m/s^2. It travels 23 m along the hill before the hill becomes more of a curve than a straight line. Given that the ball's speed after 23 m is 5.8 m/s and the time the ball took to slow down was 3.2 seconds, then determine the ball's change in height.

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.
