Experiment 2: Kinematics of Human Motion Laboratory Report Leopoldo Luis A. Gueta‚ Lady Lian Lagamayo‚ Val Ian Caleb Leus‚ Kimberly Anne C. Macarilay Department of Math and Physics College of Science‚ University of Santo Tomas España Street‚ Manila Philippines Abstract Kinematics is the branch of classical mechanics that describes the motion of bodies and systems without consideration of the forces that cause the motion. There are four activities done in this experiment. Graphical analysis

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

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
