“The most convincing proof of the conversion of heat into living force [vis viva] has been derived from my experiments with the electro-magnetic engine, a machine composed of magnets and bars of iron set in motion by an electrical battery. I have proved by actual experiment that, in exact proportion to the force with which this machine works, heat is abstracted from the electrical battery. You see, therefore, that living force may be converted into heat, and that heat may be converted into living force, or its equivalent attraction through space.”
About This Quote
Source Scientific paper: 1845, “On the Mechanical Equivalent of Heat”
Experiments showed that mechanical work (living force) can be converted to heat and vice versa, confirming energy conservation.
In simple terms: Work and heat are interchangeable forms of energy.
Key Takeaway
Recognize energy can change form but is conserved.
