    One thing I know is that gravity is the weakest force out of the four forces.

  4. When you drop something it dosent float gravity makes it drop to the ground.

  5. It makes things fall to the ground.

  15. I know that gravity is the weakest force but it is what keeps us from floating in the air.It also has to do with our air.Thats what i know!

    Gravitation, or gravity, is a natural phenomenon by which physical bodies attract with a force proportional to their mass. Gravitation is most familiar as the agent that gives weight to objects with mass and causes them to fall to the ground when dropped. Gravitation causes dispersed matter to coalesce, and coalesced matter to remain intact, thus accounting for the existence of the Earth, the Sun, and most of the macroscopic objects in the universe.
    Gravitation is responsible for keeping the Earth and the other planets in their orbits around the Sun; for keeping the Moon in its orbit around the Earth; for the formation of tides; for natural convection, by which fluid flow occurs under the influence of a density gradient and gravity; for heating the interiors of forming stars and planets to very high temperatures; and for various other phenomena observed on Earth.
    Gravitation is one of the four fundamental interactions of nature, along with electromagnetism, and the nuclear strong force and weak force. Modern physics describes gravitation using the general theory of relativity by Einstein, in which it is a consequence of the curvature of spacetime governing the motion of inertial objects. The simpler Newton's law of universal gravitation provides an accurate approximation for most physical situations.

    1. What I know about gravity is that it's the weakest of the four forces of nature, and it's also what keeps us on earth,(I think).

  24. gravity keeps us from floating everywhere.

  25. Gravity keeps things on the ground.

    ReplyDelete
  26. I know that gravity helps keep us down from floating away into space and die :)

  28. I know that if we didn't have gravity we would float.. 0.0

  29. Gravity is the reason why things fall to the ground. also gravity makes you hevyier depending on how big the peice of mass beneath your feet is .

    it's apart of life and the reasons different items fall to the ground very fast

  31. I know gravity is the reason why we stay on the ground and don't start flying into space.

  32. Alot that an apple doest float

    ReplyDelete
  33. I think newton found it.

  34. It pulls everything to a certain object or place

    ReplyDelete
  35. Larger object generate a force called gravity that makes other objects come close to it.

    ReplyDelete
  36. What I know about the force of gravity is that every object has a force of gravity and that the strength of gravity changes due to mass.

  37. it keeps you and the floor

  38. It holds everything down onto earth. It's the weakest force in the 4 forces and There is less Gravity in space and on the planets.

  39. it pulls everything no matter what its mass to the ground or what ever is below it.

    ReplyDelete
  40. I know that gravity is the force that brings things down. There is more gravity on earth than in space.

    ReplyDelete
  41. Gravity pulls everything toward the ground.
