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 of human motion, where displacement vs. time and velocity vs. time were graphed. Graphical analysis of motion where in the 10th seconds the total displacement is 6.31m, average velocity is 0.628 m/s and instantaneous velocity is 1.257m/s. Reaction time where one of the normal reaction time among the group is 0.192s and the reaction time while someone is distracting the member is 0.175s, and lastly graph matching.
1. Introduction
All of us have the ability to move. Knowing how to describe motion is an important first step in understanding the underlying physics that governs changes in motion. We see changes in motion all the time, as we go to work or school, participate in sports or even wander around our homes. If we never changed our own motion, we would never make it out of bed in the morning. The study of motion and of physical concepts such as force and mass is called Dynamics. Kinematics is one of the topics under dynamics. Kinematics describes motion without regard to its causes. In this experiment, kinematics focuses in one dimension: a motion along a straight line. This kind of motion, involves velocity, displacement, and acceleration with regards to time. The objectives of the experiment are to draw the displacement versus time graphs and velocity versus time graphs for uniform motion and uniformly accelerated motion, and to determine one’s normal reaction time and his reaction time while being distracted by others.
2. Theory

    The purpose of this laboratory was to investigate the linear relationship between the index of difficulty and movement time. Furthermore, the target width-amplitude relationship was observed. The goal was to determine the effect of task difficulty on movement time. Based on Fitts’ law, it was hypothesized that the relationship between movement time and index of difficulty would increase linearly.…

    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.…

    Therefore for Subjects 2, 4, and 6 the body is faster than average of taking impulses from the occipital lobe to the motor cortex of the brain which then produced the movement. This and different life experiences lead to the 3 subjects to be faster than the other 3 subjects. https://www.scienceworld.ca/resources/activities/reaction-time-ruler The second reaction time test is the sorting of cards in two different ways. One trial involved sorting the cards by color and the other by sorting the cards by suit the fastest.…
