Kinetic Energy only.
KE = ½ m v²

Kinetic energy. And it doesn't have to be 'massive', just have mass and be moving. Nor does it have to be moving at a constant velocity. An accelertaing object is acquiring kinetic energy and a decellerating object is losing it. But as long as they're moving, they have kinetic energy.

EDIT: Kinetic energy --IS NOT-- mass times velocity. That's called momentum. Kinetic energy is given (in Joules) by
Ek = (1/2)mv² where m is in kilograms and v is in meters/sec.

Kinetic energy, express it as massX velocity
