2. Listen to the beginning of the song of Frank Sinatra “Fly Me to the Moon”:
- What do you know about the moon?
- What do you know about gravity on the Moon? Is it different from gravity on the Earth? on the Sun?
- What do you know about other planets in our solar system? about stars? How force of gravity changes when you go from one stellar object to the other?
- Is there force of gravity in space between stars?
