To match each contribution to the theory of universal gravitation with the correct scientist:
-
Johannes Kepler: Formulated the laws of planetary motion, including the law of orbits (planets move in elliptical paths around the sun).
-
Robert Hooke: Proposed that the force of gravity is proportional to the distance between two objects and contributed to the idea of gravitational attraction.
-
Isaac Newton: Developed the law of universal gravitation, which quantitatively describes the gravitational force between two masses.
So, the correct pairings would be:
- Johannes Kepler → Laws of planetary motion
- Robert Hooke → Early concepts of gravitational attraction
- Isaac Newton → Law of universal gravitation
You can drag the names to their respective contributions as described above.
