PHYS 1405 – Conceptual Physics I Final Exam Topics Spring 2009
Review Chapters and Topics (about 40% of questions)
Ch. 1 Scientific Method and what differentiates science from other methods of inquiry. Understand the meaning of the terms hypothesis, theory, law, and fact.
Ch. 2 Newton’s 1st Law of Motion, Equilibrium Find an unknown force for an object in equilibrium
Ch. 3 Distinguish between velocity and acceleration Find the velocity at different times for a freely falling object Distance fallen for different time ratios, e.g. twice as much time is four times the distance of fall
Ch. 4 Draw/interpret force diagrams (e.g. hanging object, falling ball, etc.) Differentiate between mass and weight Apply Newton’s 2nd Law of Motion to an accelerating (or slowing) object
Ch. 5 Newton’s 3rd Law of Motion Describe and compare action/reaction pairs of interacting objects
Ch. 6 Understand momentum as a measure of total amount of motion Understand when and why the total momentum of a system stays the same and when and why it changes
Ch. 7 Principle of Conservation of Energy Energy transformations in simple mechanical situations, e.g. PE to KE Simple Machines, e.g. Lever, inclined plane.
Ch. 8-9 and 11 No questions
Ch.10 Apply distance fallen (see Ch.3) to Projectile Motion
Ch. 12 Density, Area, Volume, and Scaling Effects, e.g. speed of falling hail Elasticity and Hooke’s Law Relate stiffness of an elastic material to its length and cross-section 1 Ch. 13 Pressure-Depth Relationship Buoyancy and Archimedes’ Principle
