Gravity and Orbits
|Move the sun, earth, moon and space station to see how it affects their gravitational forces and orbital paths. Visualize the sizes and distances between different heavenly bodies, and turn off gravity to see what would happen without it!|
- Gravitational Force
- Circular Motion
Sample 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
