2. Gravity

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

4. The Earth is pulling everything towards its center.
What is gravity?
A Victim of Gravity
The Earth is pulling everything towards its center.

5. To have gravity, an object must have mass.
What is gravity?
To have gravity, an object must have mass.
Mass – the amount of matter in an object.
Everything in the universe has mass.

6. What is gravity?
Gravity keeps the Solar System & the universe together.
No gravity means no Solar System.
No gravity means no universe.

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

8. Less mass = Less gravitational pull.
What is gravity?
Less mass = Less gravitational pull.
More mass = More gravitational pull.

9. Less mass = Less gravitational pull.
What is gravity?
Less mass = Less gravitational pull.
More mass = More gravitational pull.

10. Is mass and weight the same?
What is gravity?
Is mass and weight the same?
Mass – the amount of matter in an object.
Weight – Measure of gravitational pull.

11. An object on Earth has a mass of 100 grams.
What is gravity?
An object on Earth has a mass of 100 grams.
It’s weight on Earth would be 100 grams.

12. An object on Jupiter has a mass of 100 grams.
What is gravity?
An object on Jupiter has a mass of 100 grams.
It’s weight on Jupiter would be 240 grams (2.4 x Earth weight).

13. An object on the Moon has a mass of 100 grams.
What is gravity?
An object on the Moon has a mass of 100 grams.
It’s weight on the Moon would be 16 grams
(.16 x Earth weight).

14. Jupiter has more mass than Earth.
What is gravity?
Jupiter has more mass than Earth.
Jupiter’s gravitational pull is greater than Earth’s.

15. Dwarf planet Ceres has less mass than Earth.
What is gravity?
Dwarf planet Ceres has less mass than Earth.
Earth’s gravitational pull is greater than Ceres’s.

18. You would weigh ½ of what you now weigh!
What is gravity?
What if Earth’s mass decreased to ½ of it’s current mass and the diameter didn’t change?
You would weigh ½ of what you now weigh!

19. What is gravity?
What if Earth’s mass doubled and the diameter didn’t change?
You would weigh twice as much as you weigh today!

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

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

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

23. Your weight on other planets.
What is gravity?
Your weight on other planets.
How high can you jump on other planets?
