Question

Galileo and Newton both studied the night sky. Galileo studied Jupiter and its moons. Newton studied the gravitational force that held the planets in orbit. Which of these statements best explains why the two scientists proposed different theories about the solar system?

Both had limited data.

Both had different interests.

They wanted to contradict each other's theory.

They wanted to be the first to discover new planets.

Answer 1

Both had different interests

Answer 2

Explanation :

Galileo studied Jupiter and its moons. Newton studied the gravitational force that held the planets in orbit.

Galileo constructed a telescope called Galileo's Telescopes. He also supported the Copernican theory.

Newton proposed the Universal law of gravitation. According to him, there exists a force between objects in the universe which is directly proportional to the product of masses and inversely proportional to the square of the distance between them.

i.e.

`F=G(m_1m_2)/(r^2)`

So, we can say that the two scientists proposed different theories about the solar system. This shows that they both had different interests.
