Mass |
This can be recognized by the force gravity exerts on a material object and by the object’s inertia |
|
|
Charge |
This can be recognized by the direct effect it can have on us or that we can observe it to have on inanimate objects |

|
|
Molecules |
Are composed of atoms |
|
|
Atoms |
Are composed of smaller particles or subatomic particles |
|
|
Chemical bonds |
It helds the molecule among its atoms |
|
|
Coulomb force |
