Astronomy: History and Concepts

Who categorized objects in motion into different elements?

Who introduced the idea of the round model of the Earth’s shape?

Who stated that all objects move depending on the forces acting on them?

In the geocentric model of the solar system, which celestial body is believed to be at the center?

Who attempted to measure the circumference of the Earth?

Who formulated the three laws of planetary motion based on Brahe’s extensive astronomical data?

What phenomenon explains why the sky is blue?

What type of mirror is typically found on the passenger side of newer cars?

What is the primary outcome of light passing through a material without being absorbed?

If 1 stadium is equal to 0.1577 kilometers and the Earth’s circumference is about 250,000 stadia as measured by Eratosthenes, what would be the earth’s circumference in kilometers?

Aristotle categorized objects in motion into air, earth, fire, and water?

Galileo established the idea that objects thrown in space will move upwards because of the gravitational pull acting on it?

In the geocentric model of the solar system, Earth is the celestial body believed to be at the center?

The heliocentric model of the solar system places the Sun as the celestial body believed to be at the center?

Eratosthenes successfully measured the circumference of the Earth?

Johannes Kepler formulated the laws of planetary motion based on his own observations.

Transmission occurs when light is absorbed by the atoms of a material and converted into thermal energy.

Diffused reflection is the separation of white light into colors due to refraction.

Rayleigh scattering explains why all colors are absorbed except green, which is reflected.

If 1 stadium is equal to 0.1577 kilometers, then the Earth's circumference is about 25,000 kilometers as measured by Eratosthenes.
