Title: The Force of Gravity.


1
The Force of Gravity.
  • May the Force be with you.

2
What is Gravity?
  • Gravity is a property of matter.
  • Gravity is a force of attraction

3
  • Every object pulls every other object toward it.
  • The more matter (molecules) an object contains
    the harder it pulls.

4
  • The closer an object is to another
  • the harder it pulls.

5
  • The harder an object pulls other objects, the
    heavier it is said to be.
  • Mass directly affects gravity.
  • The more mass it has,
  • the harder it will pull

6
Earth Gravity.
  • The earth is millions of times heavier than any
    object near to or upon its surface so it draws
    every such object toward it.

7
Why does Earth gravity never change?
  • The reason why gravity on Earth never changes is
    because the mass of the Earth never changes.

8
What if there were no gravity on Earth?
  • This would turn out to be a pretty bad day.
  • Without gravity, the air in the atmosphere has no
    reason to hang around, and it would immediately
    leap into space
  • Without an atmosphere, any living thing would die
    immediately and anything liquid would boil away
    into space.

9
Connecting weight and gravity
  • Mass vs. Weight Video
  • Everything weighs less on the Moon because the
    mass of the Moon is smaller than the mass of the
    Earth.
  • The more mass an object in space has, the more
    gravitation pull there is.
  • How much will you weigh on the objects in space?
