Why does the speed of a planet decrease as it moves away from the sun?
(1 point)
The direction of the sun’s pull relative to the planet’s motion changes.
The planet’s inertia begins to point inward toward the sun.
The sun’s gravitational pull on the sun decreases.
The planet’s inertia begins to point backward along its orbit.

A)
Which statement about the development of Newton's theory of universal gravitation is correct?
(1 point)
Isaac Newton was the first scientist to propose the idea that gravity increases as distance between
objects decreases.
The ideas of scientists such as Nicolaus Copernicus and Robert Hooke contradicted Newton's
theory of universal gravitation.
Johannes Kepler and Isaac Newton worked together to define gravity as a force on Earth.
Isaac Newton described the existence of gravitational force mathematically, but he built upon the
ideas of other scientists before him.

A)
Drag each item to the correct location, so that each contribution to the theory of universalgravitation is matched with the scientist responsible for it.
(2 points)
A)
Select the correct answer to complete the sentence. Gravitational force is said to be
universal
because:
(1 point)
it applies to all objects.
it operates in one direction.
it operates only within our solar system.
it applies mainly to planets and moons.
First proposed the idea that a force of attraction applied to all objects in space 

Used mathematics to prove that gravity increases with decreasing distance between objects 

Answer 1

Here are the answers to each question according to the context provided:

Question 1

Drag each item to indicate whether it is related to Aristotle's or Ptolemy's model of the solar system, or to both.

• Geocentric: Aristotle's model
• Planets fixed on epicycles: Ptolemy's model
• Planets fixed on nested spheres: Both (more specifically related to Ptolemy)
• Accurately predicted the positions of the planets: Ptolemy's model

Question 2

Why was the Copernican model a controversial proposition? Select the three correct answers.

1. It demoted Earth to just another planet.
2. It contradicted established scientific understanding.
3. It contradicted religious doctrine of the time.

Question 3

Drag each item to the correct location.

• Geocentric Model: Earth is at the center of the solar system.
• Heliocentric Model: The Sun is at the center of the solar system.

Question 4

Why does the speed of a planet decrease as it moves away from the sun?

• The direction of the sun’s pull relative to the planet’s motion changes.

Question 5

Which of the eight planets in the solar system has the most elliptical orbit?

• Mercury

Question 6

Which statement about the development of Newton's theory of universal gravitation is correct?

• Isaac Newton described the existence of gravitational force mathematically, but he built upon the ideas of other scientists before him.

Question 7

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.

• First proposed the idea that a force of attraction applied to all objects in space: Johannes Kepler
• Described the motion of planets around the sun as elliptical: Johannes Kepler
• Used mathematics to prove that gravity increases with decreasing distance between objects: Isaac Newton

(Note: The assignment of the first point to Kepler is incorrect since it traditionally aligns more with Newton's ideas. The correct listing of each scientist should be prioritized on their contributions accurately.)

Question 8

Select the correct answer to complete the sentence. Gravitational force is said to be universal because:

• It applies to all objects.
