EEn 1.1.1 Explain the Earth's motion Part 1

Front

What is Kepler's First Law of Planetary Motion?

Back

The orbit of a planet around the sun is elliptical, with the sun at one focus of the ellipse.

Front

What type of galaxy is the Milky Way?

Back

The Milky Way is a spiral galaxy.

Front

Why do some constellations appear in the night sky during different seasons?

Back

This occurs because of Earth revolving around the sun.

Front

What does Kepler's Second Law state about the motion of planets?

Back

A line segment joining a planet and the sun sweeps out equal areas during equal intervals of time.

Front

What is the shape of a planet's orbit according to Kepler's First Law?

Back

Elliptical.

Front

What is the barycenter in the context of planetary motion?

Back

The barycenter is the center of mass around which two or more bodies orbit.

Front

What is the significance of equal areas in Kepler's Second Law?

Back

It indicates that a planet moves faster when it is closer to the sun and slower when it is farther from the sun.

Front

What is the primary reason for the seasons on Earth?

Back

The tilt of Earth's axis as it revolves around the sun.

Front

What is the difference between rotation and revolution in terms of Earth's motion?

Back

Rotation is the spinning of Earth on its axis, while revolution is the movement of Earth around the sun.

Front

What is an elliptical orbit?

Back

An elliptical orbit is an oval-shaped path that a planet follows around a star.
