Force that pulls objects toward each other 

Force of gravity can change an objects speed, directon or both

All objects in the universe attract each other gravitational force. Depends on: th masses of the objects and the distance between them.

Ex. Elephant and cat- easier to pick up a cat because its mass is smaller than elephants and therefore the gravitional for is smaller.

Ex. Sun and you- sun is more massive that earth; gravitationl force doesn't affect us because distance between the sun and earth

          as mass increases, gravitation

Force ↑

            as ditance increase, gravitional force↓

measure of gravitational force on an object (here on Earth) 

             Weight changes when gravitional force changes

is the amount of matter in an object-object's mass does not change

Convert mass ot weight-multiply by 9.8

to convert weight to mass- divide by 9.8

Objects fall to the ground at the same rate because the accerleration due to gravity is the same for all objects.

A falling object accelerates at a constant rate- it falls faster and farther each second than it did the second before ( accerlation depends on both force and mass)

Acceleration due to gravity is 9.8 m/s/s
