=Instructional Goals=

1. Newton's 1st law (Galileo's thought experiment) Develop notion that a force is required to //change velocity//, not to //produce motion// Constant velocity does not require an explanation.

2. Force concept View force as an interaction between and agent and an object Choose system to include objects, not agents Express Newton's 3rd law in terms of paired forces (agent-object notation)

3. Force diagrams Correctly represent forces as vectors originating on object (point particle) Use the superposition principle to show that the net force is the vector sum of the forces

4. Statics ∑F = 0 produces same effect as no force acting on object Decomposition of vectors into components
