Topics to be covered on Exam #1-Physics I, Fall 1998 Definitions of position, displacement, velocity, speed, acceleration (both average and instantaneous) The relationships between these quantities, including: 1. calc-based (derivative, integrate), 2. graphical and 3. language based ( a particle moves to the right and is slowing down, what is the direction of the acceleration?) Constant acceleration motion in one and two dimensions including projectile motion. Make sure students understand that the optimal angle for max range is not always 45 degrees. Application of Newton's three laws including 1. 2. 3. 4. 5. Freebody diagrams Solving 2 simultaneous equations to get acceleration or tension or whatever Applications of Newton's first law Applications of Newton's third law You need to understand how a frictional force effects the acceleration of an object. You do not have to know how to calculate a frictional force using the coefficient of friction (us or uk) Circular motion at constant velocity, Centripetal acceleration, including understanding of the direction of acceleration and how velocity and radius affect the magnitude of acceleration. No banked or unbanked curves. Ferris wheel problems are fair game. Work-Calculating work done by a force. When is work positive, when is work negative? What is the meaning of positive and negative work? Work-Energy Theorem 1. graphical (find area under a F Vs X graph to get work done and change in KE) 2. language based (The same force acts on two different objects over the same distance, how are their KEs related?) Kinetic Energy in general, change in KE and using KE to calculate velocity. You should review homework assignments, class lectures, old exams, class activities and in-class demonstrations.
