Miriam Karunakaran Physics Honors Period 6 Physics Kinematics Lab Report Kinematics is the study of the motion of bodies without reference to mass or force. This lab aided students in observing kinematics by giving them a visual graph to look at from experiments previously performed. Variables used in this lab were “x” for position of the object‚ “v” for velocity of the object‚ and “a” for acceleration of the object. Understanding the graphical representation of

Kinematics Position To specify a position vector you need to specify: • Origin • Distance • Direction If using a 3D right-handed coordinate system with the origin being the reference point for the position vector‚ it is enough to specify the coordinates x‚ y and z. For a moving object the position vector is a function of time. Velocity & Acceleration • Velocity is defined as the change in position over a change in time; thus the average velocity is and the instantaneous velocity is • For motion

Angular Kinematics An object on a point that rotate a fixed axis has circular motion around the same axis. Linear quantities cannot be used for circular motion. This is due to the extended objects rotational motion rather that a particles linear motion. Circular motion‚ for this reason‚ is described in terms of the change in angular position. Except for the points on the axis‚ all the points on a rotating rigid object during any time interval move through the same angle. Many equations describing

(4pm) – Turnitin & Hard copy as ususal. The purpose of this assignment is to apply video collection techniques and kinematic analysis to sports performance. Whilst data collection was being carried out in groups‚ the data analysis and write up of the report must be an INDIVIDUAL ASSIGNMENT and must be completely your own work. Your report should include the following: Report Format Title Page: Include name‚ student number‚ module code and title of assessment Introduction: A brief introduction

Observation tube. d) Stopwatch e) Graduated cylinder THEORY Reynolds number is used to distinguish between laminar‚ transitional and turbulent flows. Re = Reynolds number V = Fluid velocity (m/s) d = Pipe diameter (0.012m) v = Kinematic viscosity (0.893 x 10-6m2/s) Laminar Flow‚ Re < 2000 Laminar flow denotes a steady condition where all stream lines follow parallel paths. Under this condition‚ the dye will remain easily identifiable as a solid core. Transitional Flow

development of engines‚ they were first used in this way. INTRODUCTION In this laboratory we will investigate the kinematics of some simple mechanisms used to convert rotary motion into oscillating linear motion and vice-versa. The first of these is the slider-crank - a mechanism widely used in engines to convert the linear thrust of the pistons into useful rotary motion. In this lab we will measure the acceleration of the piston of a lawn mower engine at various speeds. The results exemplify a simple

Kinematics is motion. We are in a world full of motion. You jump up‚ and there is a counteracting force that will move you down. Drop a ball‚ and the ball will fall to the ground. Push on a shopping cart‚ and the cart moves forward. These are all examples of motion‚ but there is a lot more to it than just being at rest or being in motion. One example of kinematics in the real world is in roller coasters‚ a thrill-seeking pastime for many. First‚ to understand how a rollercoaster works‚ one must understand

E102-MOTION ALONG A STRAIGHT LINE GUIDE QUESTIONS: 1. From the data obtained‚ what is the effect of the height of the track to the cart’s acceleration? The data shows that sinӨ‚ which is dependent on the height‚ is getting higher as acceleration is increasing. This implicates that when object is at higher altitude‚ its acceleration is faster. 2. From the data obtained‚ how is time‚ t related to the inclination of the track? Explain why? Time and position of velocity are interrelated to
