<span>The function of an electric motor is to change electrical energy
into
kinetic energy.
Even if you want to use the electric motor to give a heavy weight
a lot of potential energy, by lifting it up onto, say, the roof of a house,
you still have to use the motor to MOVE the weight. So you're still
giving it kinetic energy as an intermediate step..

The wave propagates outward horizontally across the surface of the pond. As you can see from the ripples, the water molecules move up and down, <em>perpendicular to the horizontal movement of the wavefronts</em>.
By definition this is a transverse wave.
