How does gravity affect the motion of a ball thrown into the air?

• It causes the ball to keep moving upward indefinitely.

• It pulls the ball back down after it reaches its highest point.

• It makes the ball stop moving.

• It has no effect on the ball's motion

What is the main difference between how we see the Sun compared to other stars?

• The Sun is the only star that produces light.

• The Sun appears much bigger and brighter because it is closer to Earth.

• The Sun is the largest star in the universe.

• The Sun is the only star that moves across the sky.

Which of the following scenarios best illustrates the concept of gravity being overcome?

• A rocket launching into space

• A stone sinking in water

• A leaf falling from a tree

• A balloon rocket heading towards the ground

Maria and her classmates built small model rockets using paper tubes and water bottles. On launch day, they pumped air into the bottles and launched the rockets straight up into the sky. Maria noticed that each rocket rose high but always came back down. She wondered why the rockets didn’t just keep flying forever.

Their science teacher explained, “When you launch your rocket, the force from the air pushes it up, overcoming gravity for a moment. But gravity doesn’t go away—it pulls the rocket back down once the upward force runs out.”

What does Maria's rocket experiment show about the force of gravity?

• Rockets can always overcome gravity.

• Gravity pulls objects up and down.

• Gravity can be overcome for a short time, but it always pulls objects back down.

• Rockets will overcome gravity even if they are out of fuel.
