39 People Who Just Learned Gravity Is A Bitch

Sir Isaac Newton would be proud.

1. Everyone has to learn about gravity sometime!

2. Some people learn about it when they’re young.

4. This co-ed just learned that gravity causes you to accelerate at 9.8 meters per second squared.

5. This young man just learned that that is really fast!

6. This tree just taught this gentleman that all falling objects travel at 9.8 m/s squared, regardless of size.

7. So gravity is a great equalizer.

8. Sir Isaac Newton was the first to accurately describe how gravity works in 1690. This boy just figured it out in 2013.

9. Newton’s gravitation equation is F = Gm1m2/r2.

10. Where “F” is the force due to gravity, between two masses.

11. Which are a distance “r” apart

12. “G” is the gravitational constant that will always be there.

13. This cat just learned that gravity is dependent on mass differential.

14. And the young man in the middle just learned the force of gravity is dependent on distance between objects.

15. Acceleration due to gravity on the surface of the earth is g = GM/r2.

ID: 932055

16. Where “M” is the mass of the Earth.

ID: 932049

17. And “r” is the radius of the Earth (or distance between the center of the Earth and you, standing on its surface).

ID: 932053

18. And “G” is the gravitational constant.

ID: 932087

19. These two making out just learned about gravitational acceleration!

ID: 932241

20. Einstein’s theory of general relativity (GR) is Gμν = 8πG/c4 Tμν.

ID: 932056

21. It is a very accurate theory of gravity.

ID: 932052

22. Where “G” (without the subscripts) is the gravitational constant.

ID: 932094

23. And “c” is the speed of light.

ID: 932237

24. This young lady just learned that Einstein was right!

ID: 932246

25. Gravitational Potential Energy is Eg = mgh.

ID: 932058

26. Where “m” is mass of object…

ID: 932059

27. …”g” is acceleration due to gravity…

ID: 932092

28. …”Eg” is the amount of gravitational potential energy an object has when it is near the surface of the Earth…

ID: 932093

29. …and “h” is height of object above the surface of Earth.

ID: 932099

30. Marines now know about gravitational potential energy!

ID: 932119

31. Large objects in the universe are also subject to gravitational acceleration: a = √(GMa0/r)

ID: 932100

32. Where where “a” is the acceleration an object feels…

ID: 932114

33. …”M” is the mass of a galaxy…

ID: 932115

34. …”r” the distance between the object and the center of the galaxy…

ID: 932238

35. …and “G” is the gravitational constant.

ID: 932121

36. This cameraman does not appreciate the mass of the universe.

ID: 932245

37. Sadly, none of these equations can determine the acceleration of gravity between two bros.

ID: 932267

38. So keep it up, guys…

ID: 932256

39. You’re gonna nail it someday!
