Gravity Orbits

What are three things all planets have in common?

• they are spherical, they have at least one moon and they have gravity

• Orbit the sun, massive enough that their gravity controls all objects in the area and they are spherical

• they have at least one moon, they are spherical and they were made by accretion

• they are spherical, they orbit the sun and they have living organisms 

Two factors effecting the magnitude of the force of gravity between 2 objects are...

• mass and distance 

• mass and matter

• distance and weight 

• weight and mass

As distance between two objects increase the pull of gravity ___________.

• Increases

• Decreases.

• Doesn't change

What would happen to Earth if the Sun's gravity dissappeared?

• Earth would continue to orbit in our Solar System normally.

• Earth would sit motionless and not moving.

• Earth would drift off in space because nothing would hold it in the Solar System.

• Earth would move toward the Sun and eventually crash into it.
