• Earth’s center.

• Outer space.

• The equator.

Patterns that can be created by force are...(choose all that apply).

• Motion in one direction.

• Shifting back and forth.

• Remaining still.

• Moving in cycles

Gravitational interaction is caused by

• Earth’s magnetic field

• Earth’s rotation

• Earth’s atmosphere

• the interaction between two masses

Two apples are sitting near each other on the ground. There is a gravitational interaction

• Between the two apples that keep them apart

• Between the two apples that causes them to move toward each other

• Between the two apples, but you don’t notice it because it is so small

• Only between the Earth and each apple. The apples do not have a gravitational interaction between them.

Earth orbits the Sun because there is a

• Gravitational pull from the sun on the earth. The earth is pulled toward the sun, rather than going off in a straight line.

• Gravitational pull from the sun on the earth. The sun pulls the earth in the direction of the earth’s orbital path.

• Gravitational push from the sun on the earth. The sun pushes the earth away so it does not crash into the sun.

• Strong magnetic interaction between the sun and the earth. The gravitational interaction between the sun and the earth is small.

Choose all that are true about gravity.

• Affected by mass and distance

• Large masses have a stronger gravitational pull

• Small masses have a stronger gravitational pull.

• Large distances have a weak gravitational pull.

• Small distances have a stronger gravitational pull.
