Student Learning Objectives

• To recognize what does and does not constitute a force.
• To understand and use Newton's 1st, 2nd, and 3rd laws.
• To identify the specific forces acting on an object and draw an accurate free-body diagram.
• To identify action/reaction pairs of forces.
• To begin the process of understanding the connection between force and motion.
• To distinguish mass, weight, and gravity.
• To learn and use simple models of friction and drag.
• To recognize and solve simple equilibrium problems.
• To apply the full strategy for force and motion problems to problems in single-particle dynamics.
• To learn how two objects interact.
