What is Gravity? | 2nd Grade Reading Comprehension Worksheets - Free Printable

Problem Overview:

The task involves answering five questions based on the provided reading passage about gravity. The passage explains what gravity is, how it works, and its effects on objects, people, and celestial bodies.

Solution:

#### Question 1: Why do your feet stay on the ground instead of floating?
- Answer: Your feet stay on the ground because of gravity. Gravity is a force that pulls objects toward each other. Since Earth is much larger than you, it exerts a strong gravitational pull on you, keeping you grounded instead of floating in space.

#### Question 2: Who was the scientist who did experiments with gravity and motion many years ago?
- Answer: The scientist who conducted experiments with gravity and motion many years ago was Sir Isaac Newton. He observed and studied the way things move and fall on Earth, leading to his famous laws of motion and the concept of gravity.

#### Question 3: Why are things and people attracted to Earth?
- Answer: Things and people are attracted to Earth because of gravity. Gravity is a force that attracts all objects to each other. Since Earth is very large and has a significant mass, it exerts a strong gravitational pull on smaller objects like people and other things, causing them to be attracted to and stay on the surface of the Earth.

#### Question 4: What can we see in the sky because of gravity?
- Answer: We can see the moon in the sky because of gravity. The Earth's gravity pulls the moon toward it, keeping the moon in orbit around the Earth. Without gravity, the moon would drift away into space.

#### Question 5: What would it be like if there were no gravity on Earth?
- Answer: If there were no gravity on Earth, several things would happen:
- People and objects would float in the air instead of staying on the ground.
- There would be no atmosphere, as gravity holds the air molecules close to the Earth's surface.
- The moon would not orbit the Earth and would drift away into space.
- Walking or standing would be impossible, as there would be nothing to keep us grounded.
- Everyday activities like pouring water or eating food would be chaotic, as objects would not stay in place.

Final Answers:

1. Why do your feet stay on the ground instead of floating?
Answer: Because of gravity, which pulls objects toward the Earth.

2. Who was the scientist who did experiments with gravity and motion many years ago?
Answer: Sir Isaac Newton.

3. Why are things and people attracted to Earth?
Answer: Because of gravity, which attracts all objects to each other, and Earth's large mass creates a strong gravitational pull.

4. What can we see in the sky because of gravity?
Answer: The moon, which orbits the Earth due to gravity.

5. What would it be like if there were no gravity on Earth?
Answer: People and objects would float, there would be no atmosphere, the moon would drift away, and everyday activities would be impossible.
