energy

Deductions

• spacetime has quality energy ⇐ (spacetime is a continuum), (continuum has quality energy)
• non-material physical substance has quality energy ⇐ (non-material physical substance is subclass of physical substance), (physical substance has quality energy)
• continuum has quality energy ⇐ (continuum is subclass of physical substance), (physical substance has quality energy)
• chemical energy is subclass of energy ⇐ (chemical energy is subclass of mechanical energy), (mechanical energy is subclass of energy), (is subclass of is a transitive relation)
• food energy is subclass of energy ⇐ (food energy is subclass of potential energy), (potential energy is subclass of energy), (is subclass of is a transitive relation)
• potential energy is subclass of energy ⇐ (potential energy is subclass of mechanical energy), (mechanical energy is subclass of energy), (is subclass of is a transitive relation)
