Net Force

Net force is the vector sum of all forces that act on an object,
including friction and gravity. When forces are applied in the
same direction they are added. For example, if two 10 lb forces
were applied in the same direction the net force would be 20 lb.

If 10 lb of force were applied in one direction and 5 lb of force
applied in the opposite direction, the net force would be 5 lb
and the object would move in the direction of the greater force
