Standing on a Floor


Key to the possible choices of force

Fair - air resistance Fs - force of static friction- this is your choice if an object is being pushed or pulled but not moving Fa - the applied force: any push or pull Fk - kinetic friction: this is your choice if there is friction and the object is moving Fg - the force of gravity Ff - the force of friction. Could be kinetic or static FN - the normal force FT - the force of tension. Use this if there is a string or cable involved Fnet - not really a force, just the sum of all of the vectors added together. This is the final force
