Solar System and Gravity Review

If a spacecraft travels from Earth to the edge of the Solar System, what will happen to the gravitational pull between Earth and the spacecraft? The gravitational pull between Earth and the spacecraft will...

• increase

• decrease

• become zero

• remain the same; no difference will occur

A person would weigh more on Jupiter than on the Earth because . . .

• Jupiter has more mass, and therefore more gravity

• Jupiter has less mass, and therefore more gravity

• Jupiter has more mass, and therefore less gravity

• Jupiter has less mass and therefore less gravity

Develop a model to describe the role of gravity in the motion of planets within the Solar System. Include the Sun and at least two planets in your model.

• A model showing planets moving in straight lines away from the Sun.

• A model showing planets orbiting the Sun in elliptical paths due to gravitational pull.

• A model showing planets stationary in space.

• A model showing planets moving randomly in space.
