I think you mean Inertia?
Newton's First law of motion states that:
"An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an external force."
This means that there is the natural tendency of objects to resist changes in their state of motion. This tendency to resist changes in their state of motion is described as inertia
inersia
Backward force is called "retrograde" force.

The inertia switch on a 1985 Mercedes 500 SEL is located in the passengers side kick panel.
On a 2003 Ford Expedition : The fuel pump inertia switch ( shut off switch ) is located in the cargo area , on the drivers side , near the liftgate , behind the access panels
inertia pulls Earth strait while gravity pulls the earth toward the sun which make earth rotate around the sun for example: http://s1107.photobucket.com/albums/h387/Colista1234/?action=view&current=sun-1.jpg
Friction is the force that works against motion. It occurs when two surfaces rub against each other, creating resistance that opposes the direction of motion. Friction can slow down or stop the movement of an object.
Well, depending on which way you are pushing, it could be one of three forces. If you are pushing along a table, then it is friction that is preventing the box from moving (or more accurately, static friction). If you are pushing the box down into the table, then it is the normal force that is at work. If you are pushing into the air, then it is gravity.
