PHY 105 Conceptual Physics

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
