Inertia is: 

• Is a property of matter, the more mass an object has the more force is required to move the object.
• The resistance that one surface has when moving over another surface.
• Is a force which tries to pull two objects toward each other.

Friction is 

• Is a property of matter, the more mass an object has the more force is required to move the object.
• The resistance that one surface has when moving over another surface.
• Is a force which tries to pull two objects toward each other.
