Question

through scientific observation of the natural world, isaac newton identified these laws
gravitation and motion
planetary orbit
the social contract
atomic energy

Explanation:

Isaac Newton is renowned for his work in physics. His laws of motion (three fundamental laws) and the law of universal gravitation are cornerstones of classical physics. Planetary orbit concepts were influenced by his work but are more of an application. The social contract is a philosophical - political concept (e.g., Rousseau's work). Atomic energy is related to later scientific developments like quantum mechanics and nuclear physics.

Answer:

gravitation and motion
