9. 9.Mikaela is a skydiver. Mikaela has jumped out of airplanes many times from different heights in the sky. The arrows show which direction Mikaela falls each time she jumps. What does this tell you about gravity?

• When Mikaela jumps from a distance that is farther away from the surface of the Earth, the direction of gravity changes.

• When Mikaela jumps from a distance that is farther away from the surface of the Earth, the direction of gravity never changes.

• When Mikaela jumps from a distance that is farther away from the surface of the Earth, the strength of gravity increases and she falls faster.

• When Mikaela jumps from a distance that is farther away from the surface of the Earth, the strength of gravity decreases and she falls slower.

10.Mikaela decides to do an experiment. As she flies in the airplane, she drops different objects to see what happens. She drops a tennis ball, a feather, a paper clip, and a magnet. She watches what happens to each object. The arrows show which direction each object falls after it is dropped from the airplane. What does this tell you about gravity?

• Gravity only pulls heavy objects down toward the surface of the Earth.

• Gravity only pulls light objects down toward the surface of the Earth.

• Gravity only pulls magnetic objects made of metal toward the surface of the Earth.

• Gravity pulls all objects down toward the surface of the Earth.
