|
The force of gravity between Earth and the object
|
|
How to find mass of a book
|

|
|
A Newton
|
A unit of measurement of the force of gravity between two objects that apply a push or pull
|
|
An object's weight can change due to its ______________ in the unverse
|
Location
|
|
Would you weigh more or less on the moon? Why?
|
Less on moon because the moon has less mass than Earth so the force is less.

|
|
An objects mass is dependent upon the type of _______________ it has
|

|
|
If an object has many packed particles in a small space, the density has high or low density
|
High
|
|
Low density means....
|
Only a few particles in a certain amout of space
|
