Kinematics

Questions: Answer all questions given What kind of relationship did you see in your D vs T graphs (both hand and computer)? Do these relationships make sense? Explain! In the distance versus time graph for the hand graph, there is an exponential increase the in the distance traveled; as time progresses, the distance the car travels increases a little more, as the slope is not a straight line, but instead slopes upwards, with slopes later in the line being steeper than the slopes before. What…

My ride is entitled, Arctic Rush. The ride contains a Winter theme that will remind you of the season. Throughout the ride, you will go up a mountain, swirl around a humongous snowman and a gigantic penguin, dodge icicles, and go through snow while riding in an icicle. My ride has a hydraulic launch at the beginning that will instantly shoot you up the mountain, and throughout the roller coaster. You will be moving at a top speed of 100 miles per hour throughout the ride, which will allow you to…

As the height of the ramp increased, the speed, velocity, and acceleration also increased. In Run 1, the height of the ramp was highest at 5 textbooks. Evidence: The speed and velocity of the car in this lab are essentially the same because the total distance traveled is equal to the total displacement of the car. In Run 5, the ramp had the lowest height of one textbook. Using the slope of the position versus time graph, the speed of the car from Run 5 to Run 1 was calculated to 0.439 m/s, 0.745…

Introduction: Recent studies reported that the kinematic alignment of an implant is more physiological than the traditional methods, and therefore results in better clinical outcomes. They found that for kinematic alignment of the implant, the femoral component should be positioned varus 2.3 degrees and tibial component in valgus 2.4 degrees without any rotation. Howell et al also claimed that kinematically aligned TKA does not cause any significant failure; rather, it restores the function of…

a variety of theoretical perspectives, I will use the physics topic of kinematics because it includes all the disciplines of STEM. Kinematics is science of describing the motion of all objects in a variety of ways. The subtopics within…

Biodiesel which is an alternate fuel, is produced…

R.W.Barfield (1998) Biomechanics of kicking in soccer. The objective of the study was to examine the effect of angle of approach on kicking accuracy. Accuracy kicking is necessary for successful kicks from penalty mark. The study included 7 male amateurs recreational soccer player aged 26+/- 3years, body mass 74-80 kgs, stature 1.74 +/- 0.06 m, who were right foot dominant. Kicking kicks from penalty mark at 0.6x0.6 target at the full size goal post according to their self selected approach…

Literature demonstrates that pitch types (fastball, curveball, change-up, slider) generally have similar kinematics with only minor differences in forearm and wrist action, and even less so in the elbow and shoulder(36-40). Fleisig et al demonstrated in a kinematic study involving 21 collegiate baseball pitchers that the change-up pitch is the least stressful, while the curveball and fastball have similar elbow and shoulder kinetics, with the curveball exhibiting increased forearm supination and…

The focus of the video clip we chose is around kinematics and dynamics. The movie scene we chose to do is from Project X when Thomas jumps from the roof and lands on a bouncy house. The research we did in order to determine whether or not Thomas’ fall was survivable centered around finding numbers pertaining to Thomas’ weight, the average height of a two story house, and information about fatal falls. We picked this scene because we wanted to see how realistic the fall was. To get the numbers we…

Introduction The shoulder contains complicated groups of muscles, tendons, ligaments, and bursae all involved in humeral and scapular kinematics (Terry & Chopp, 2000). Regular use of the arms can result in fatigue of shoulder musculature, which could lead to altered scapular kinematics during humeral elevation (Tsai, McClure, & Karduna, 2003). These changes in scapular kinematics can potentially lead to shoulder problems such as impingement syndrome, rotator cuff tears, and glenohumeral…
