Drag each item to the correct location, so that each contribution to the theory of universal gravitation is matched with the scientist responsible for it.
Johannes Kepler Robert Hooke Isaac Newton
First proposed the idea that a force of attraction applied to all objects in space
described the motion of planets around the sun as elliptical
used mathematics to prove that gravity increases with decreasing distance between objects
Johannes Kepler - described the motion of planets around the sun as elliptical
Isaac Newton - First proposed the idea that a force of attraction applied to all objects in space and used mathematics to prove that gravity increases with decreasing distance between objects
Robert Hooke - N/A
are you sure
Yes, I am confident in my response. Johannes Kepler described the motion of planets around the sun as elliptical, Isaac Newton first proposed the idea of a force of attraction applying to all objects in space (universal gravitation), and he also used mathematics to prove that gravity increases with decreasing distance between objects. Robert Hooke made significant contributions to the field of physics, but his work did not specifically relate to the theory of universal gravitation.
which model is which
Aristotle's Model Ptolemy's model
Aristotle's Model - The Earth is at the center of the universe, and other celestial bodies revolve around it in perfect circular motions.
Ptolemy's Model - The Earth is at the center of the universe, and celestial bodies move in complex orbits called epicycles to explain their observed motions.
First proposed the idea that a force of attraction applied to all objects in space:
- Isaac Newton
Described the motion of planets around the sun as elliptical:
- Johannes Kepler
Used mathematics to prove that gravity increases with decreasing distance between objects:
- Robert Hooke
To match each contribution to the theory of universal gravitation with the respective scientist, we can analyze the statements provided.
1. "First proposed the idea that a force of attraction applied to all objects in space"
This contribution refers to the concept of universal gravitation itself. Isaac Newton was responsible for formulating this foundational idea, so the correct match is:
- Isaac Newton
2. "Described the motion of planets around the sun as elliptical"
This statement relates to the study of planetary motion. Johannes Kepler's laws of planetary motion provided a framework for understanding the elliptical paths taken by planets around the sun. Therefore, the correct match is:
- Johannes Kepler
3. "Used mathematics to prove that gravity increases with decreasing distance between objects"
This contribution relates to the mathematical understanding and proof of how gravity varies based on the distance between objects. Robert Hooke made significant contributions to understanding gravity, including the inverse square law of gravitational attraction, which states that gravity increases as the distance between objects decreases. Thus, the correct match is:
- Robert Hooke
Matching contribution to scientist:
- First proposed the idea that a force of attraction applied to all objects in space: Isaac Newton
- Described the motion of planets around the sun as elliptical: Johannes Kepler
- Used mathematics to prove that gravity increases with decreasing distance between objects: Robert Hooke
