Gravity & Orbits

Let’s examine how gravity effects orbits. The common misconception about gravity is that it’s a pulling force, which isn’t quite accurate. Gravity is more of a literal warping of the spacetime fabric.

Topics

• Gravitational Force
• Circular Motion
• Astronomy

Learning Goals

• Describe the relationship between the Sun, Earth, Moon and space station, including orbits and positions
• Describe the size and distance between the Sun, Earth, Moon and space station
• Explain how gravity controls the motion of our solar system
• Identify the variables that affect the strength of gravity
• Predict how motion would change if gravity was stronger or weaker
