2 Gravity and the Solar System

3 What is gravity? The force that attracts one object to another. Science, Please!

4 Everything that has mass has gravity. The Earth is pulling everything towards its center. What is gravity?

5 This means everything in the universe has gravity. What is gravity? Gravity keeps the Solar System together. No gravity means no Solar System.

6 Why can the Solar System exist? What is gravity? Why doesn’t the Moon fall down?

7 The smaller the object, the less the mass. What is gravity? The less the mass the object has, the weaker the gravity.

8 The larger the object, the more the mass. What is gravity? The more mass the object has, the stronger the gravity.

9 The less massive the object, the less you would weigh. What is gravity? The more massive the object, the more you would weigh.

10 If you weighed 100 pounds on Earth, you would weigh 240 pounds on Jupiter. (100 x 2.4) What is gravity?

11 If you weighed 100 pounds on Earth, you would weigh 16 pounds on the Moon. (100 x.16) What is gravity?

12 The closer to the Sun, the faster the object travels. What is gravity? The farther from the Sun, the slower the object travels.

13 Mercury, the planet closest to the Sun, takes 88 Earth days to revolve once around the Sun. What is gravity? Neptune, the planet farthest from the Sun, takes 165 years to revolve once around the Sun.
