Ch. 05 Applying Newton's Laws
Learning Objectives
- Be able to describe common types of interactions (Weight, Force, Tension, Normal forces) as vectors; explicitly identifying the two objects that interact. This involves use of magnitude/direction and component forms; graphical and/or component vector addition to find the net force.
- Know when and be able to apply Newton's first law to the net force on an object undergoing constant velocity motion.
- Know when and be able to apply Newton's second law to the net force on an object undergoing constant acceleration motion.
- Know when and be able to apply Newton's third law in describing a given interaction two different ways, involving the two objects that interact, and how this law "connects" two separate free-body diagrams.
- Demonstrate mastery of applying Newton's laws using free-body diagrams to analyze the behavior/motion of particles.
- Demonstrate mastery of applying Newton's first law to analyze equilibrium situations.
- Demonstrate mastery of applying Newton's second law to analyze dynamic situations.
- Understand how frictional forces can be modeled for different situations (kinetic sliding, static sliding, and drag).
- Demonstrate mastery of applying Newton's laws to analyze motion involving frictional/drag forces.
