PPT-S3 Physics Measuring Acceleration

The Equation Describe how you could measure the acceleration of a small vehicle as it runs down a slope in the laboratory TASK Many different ways httpswwwyoutubecomwatchvYUqwdD73610 There are different ways to measure acceleration here are a few. Poynting. . dominated jets. Yuri Lyubarsky. Ben-Gurion University. Beer-Sheva, Israel . 1. What . are the conditions for acceleration and collimation?. 2. What . is the final collimation angle?. TODAY:. Acceleration. Grading Scale for Physics11 . (it might change) . 2013/2014. Assignments (. worksheets, labs, homework, pop-quizzes. ) 15%. Quizzes (. around 25 of them. ) 20%. Unit Tests (. MECHANICS:. DYNAMICS. Uniform Circular Motion. Motion in a circular path at constant speed. Speed constant, velocity changing continually. Velocity changing direction, so there is acceleration. Called . Chapter 2. Kinematics: Description of Motion. Warmup. : . Movin. ’ On. Acceleration . refers to any change in an object’s velocity. . Velocity . not only refers to an object’s speed but also its direction. The direction of an object’s acceleration is the same as the direction of the force causing it.. Alexei Safonov. Lecture . 9: . Dynamics. Kinetic Friction. For kinetic friction, it turns out that the larger the . Normal Force. the larger the friction. We can write. F. Friction. = . m. Kinetic. If the net force is ZERO we say the system is ___________________ and the object will . __________________..  . If the net force is NOT zero we say the system is ________________ and the object will . ACT/PSAE practice. Intro to acceleration. What does it mean in common language?. What does it mean to a physicist? (That’s you!). First equation of acceleration. A = v/t. Standard unit for acceleration: m/s^2. Material on Final Exam. Section 1: Measuring Motion. Objectives:. Describe the motion of an object by the position of the object in relation to a reference point. Identify the two factors that determine speed. up a clicker!.
