What keeps our Earth in orbit around the Sun, rather than flying off into space in a straight line?

• The tendency for an object to stay in motion unless acted upon (inertia).

• The lack of air resistance in space.

• The gravitational pull from the Sun.

• The gravitational pull from the center of the Milky Way.

• increases

• decreases

• stays the same

As the distance between two objects INCREASES, the amount of gravitational pull between them:

• increases

• decreases

• stays the same

As the distance between two objects DECREASES, the amount of gravitational pull between them:

• increases

• decreases

• stays the same

Your weight depends on the _______. (Pick the BEST answer.)

• thickness of the atmosphere

• inertia of the planet

• pull of gravity

• mass of your body

What keeps the Earth orbiting the Sun from a safe distance, rather than getting pulled into it by the Sun's gravitational pull?

• The gravitational pull from Jupiter and Saturn balancing out the pull from the Sun.

• The fact that Earth is always moving forward at the same speed (has inertia).

• The Sun isn't pulling on Earth, we just keep moving in circles because that's our orbit.

• The Earth is always being repelled by the Sun, which keeps us far from it.

When will the forces of gravity between two objects be the GREATEST?

• When the masses of both objects are small and the objects are far apart.

• When the masses of both objects are large and the objects are close together.

• When the masses of both objects are small and the objects are close together.

• When the masses of both objects are large and the objects are far apart.
