It is. There isn't really such thing as just "energy," though. It comes in many different forms. Kinetic, potential, nuclear, thermal, ionization, and so many more. From wikipedia:a property of objects which can be transferred to other objects or converted into different forms, but cannot be created or destroyed.[1] The "ability of a system to perform work"

Physical is generally accepted to mean "tangible," i.e., something which one is able to touch and feel - over physical as "part of physics." I agree, it's just - odd for me to see the word "physical" used to mean, more esoterically, "relating to or of physics." I'm sure both meanings are correct, but one is more common.
