Gravity and Inertia

Which of the following would cause more gravitational attraction between Jupiter and one of its moon, Io?

• Increasing the distance between Jupiter and Io

• Increasing the mass of Jupiter

• Decreasing the mass of Io

• Decreasing the distance of Io from the Sun

Why does the Moon orbit Earth instead of the Sun?

• Gravity depends on distance and the Moon is closer to Earth.

• Only large objects orbit around the Sun and the Moon is too small.

• The Moon used to be part of Earth so it must orbit Earth.

• The Moon is moving too fast and cannot change its orbit.

The Sun's gravity holds each planet in its orbit. Neptune is at a farther distance from the Sun than Earth is. How does the effect of the Sun's gravity on Neptune compare with the effect of the Sun's gravity on Earth?

• The Sun has the same gravitational pull on all planets that are in orbit.

• The Sun has more gravitational pull on Neptune because it is larger.

• The Sun has less gravitational pull on Earth because it is closer.

• The Sun has less gravitational pull on Neptune because it is farther away.
