Conservation of energy

Independently

Perpetual entropy

Galileo’s analysis of “interrupted pendulum” in 1638, Christian Huygens’s laws of collision in 1669, Gottfried Wilhelm Leibniz’s conservation of mass times velocity (in systems where the masses don’t interact) between 1676 and 1689, Isaac Newton’s assumption of the exact conservation of mechanical momentum in 1687, Johann Bernoulli’s law of conservation of vis viva in 1715, Daniel Bernoulli’s principle of virtual work in 1738, Émilie du Châtelet (1706 – 1749) hypothesis of the conservation of total energy, as distinct from momentum, in 1740, the Lagrange-D’Alembert’s principle of classical mechanics (a general case of Newton’s second law, F=ma) in 1742, all led to understanding energy and the laws of thermodynamics.
