## Key to the possible choices of force

F

_{air}- air resistance F_{s}- force of static friction- this is your choice if an object is being pushed or pulled but not moving F_{a}- the applied force: any push or pull F_{k}- kinetic friction: this is your choice if there is friction and the object is moving F_{g}- the force of gravity F_{f}- the force of friction. Could be kinetic or static F_{N}- the normal force F_{T}- the force of tension. Use this if there is a string or cable involved F_{net}_{ }- not really a force, just the sum of all of the vectors added together. This is the final force## Standing on the Floor
