What is Orbit? - Planets & Satellites

1. What is Orbit? - Planets & Satellites

This lesson talks about what an orbit is and defines some common terms associates with orbit. We also talk specifically about orbits of planets and satellites.

How Orbits Are Influenced by Gravity & Energy

2. How Orbits Are Influenced by Gravity & Energy

This lesson will explain how potential energy, kinetic energy, speed, and gravity are linked to the orbital motion of planets in our solar system. It will also define aphelion and perihelion.

Identifying & Calculating Time Zones

3. Identifying & Calculating Time Zones

Knowing the time zones is very important for communication. To be able to identify and calculate time zones, you must know terms like lines of longitude, prime meridian and the International Date Line.

The Cycle of the Seasons in Astronomy

4. The Cycle of the Seasons in Astronomy

This lesson will explain to you why the Earth has different seasons, what the equinoxes and solstices are, their names, and if the distance the Earth is from the Sun influences the seasons.

The Sun's Angle & Movement

5. The Sun's Angle & Movement

After watching this video, you will be able to explain how the Sun's movement in the sky varies with the seasons and how that relates to the length of each day. A short quiz will follow.

Predicting When The Moon Will Rise and Set

6. Predicting When The Moon Will Rise and Set

In this lesson, you'll learn when the moon will rise or set during four distinct phases: full moon, new moon, first quarter moon, and third quarter moon.
