1. Suppose a force of 8 N east, a force of 12 N west, and a force of 4 N east act on a moving object. Use different colors of markers to model the forces on the object. What is the net force of the object? Are the forces you modeled balanced or unbalanced? Will the forces change the object's motion?

2. Model examples of balanced and unbalanced forces acting on an object. In each case, decide which forces will act on the project. For each examples, determine the net force, and decide if the forces are balanced or unbalanced. Then decide if the forces will change the object's motion.
