A ball rolling down a hill.
Kinetic energy is energy of motion. The ball is moving macroscopically, so it has kinetic energy. The tank of gasoline and the battery store chemical energy (and the reservoir stores gravitational potential energy); while molecules have microscopic kinetic energy, those examples are usually meant as stored (potential) energy.
