What's Gravity got to do with it, anyway?

This is a gravity map of the world.  The red spots indicate places where gravity is less powerful, and the blue spots indicate places where gravity is more powerful.  What is gravity, anyway, and what does it have to do with Newton's laws?

  1. i think gravity is pulling so you stay in place? i have no idea

  2. gravity is a force that keeps things on the earth from flying away

    it is a pushing force since it is pushing down on you

  3. Gravity is what keeps us on the ground. And i have no idea what it has to do with Newton's Laws.

  4. Gravity is a pull that keeps you from floating off in space
    It goes with newtons law wat goes up must come down because gravity keeps us on the ground

  5. gravity is the force that is keeping us on the earth. It pulls us tword the center but not enough for us to get pulled through the ground. it helps things stay balanced.

  6. === Gravity is what holds you down and keeps you from flying away.....
    FOr newtons laws it keeps things balanced and unbalanced?

  7. gravity is a force pulling together all matter
    because gravity is outside the force acting on the object

  8. it is a from that houlds us down on the erath it pull frocw

  9. its a form of energy that holds us down on the earth it is a pull force because it pulls us to the ground

  10. It is a force that pushes down on to Earth's surface. If there was know gravity Newtons Laws would not work.

  11. gravity is the force that keeps you on the ground
    if there was no gravity objects would keep moving forever

  12. gravity is what keeps us on the ground. The more mass an object has, the more gravity it makes, and since watter is heavier than ground, it is denser and has more mass, causing more gravity.
    so mountions have much more ground thatn water, so they have less gravity, while the oceasn has more water, cause more gravity.

    with newtons law, it keeps you where there is more friction(ground/floor) and puts an incessant force pointing down.

  13. gravity-is the magnetic force that surrounds the earth.
    it is what makes us fall when we jump out of a plane or when we jump in the air.

  14. It is a form of energy that holds us down to the earth. It deals with newtons law by the gravity not letting something go on forever and ever. Slows something down.

  15. Gravity:Gravity is a force pulling together all matter

  16. -gravity is the force that pulls things to the center of the earth...with out it we would float into space...
    Newtons 1st law--the opbject would stay in motion until it was effected by gravity

  17. its a pull which keeps things on the earth. what goesa up must come down

  18. Gravity is the force that pulls things down to the earth. Gravity is a force that acts upon a force to stop or slow something down, that is what it has to do with newton's law.

  19. gravity is the force that pulls you to the earth Newton's what goes up must go down
