Find velocity vx(t) and coordinate x(t) for a particle of mass m which is subject to the force given by: fx = f0 e −kt , where f0 and k are known constants. the initial conditions are x = 0 and v = 1 at t = 0.

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.

Athermometer to measure the temperature of course
