Kinematics

It is divided in two phases, the stance phase and the swing phase. During the stance phase, the lower extremity is in contact with the ground. This phase is formed by 5 different stages (the Heel Strike, Foot Flat, Mid Stance, Heel Off and Toe Off) which form the whole movement. In contrast, during the swing phase, the current limb, is not in contact with the ground. This phase has three stages ( Acceleration, Mid Swing and Deceleration) that generates the entire movement. • The aim of this study is to investigate the kinematic and kinetic differences in barefoot and shod running. It has been hypothesized that there will be significant kinematic and kinetic differences between barefoot and shod running . It has been hypothesized that there will be no significant kinematic and kinetic differences between barefoot and shod running Methods: Participants: The participants that took part on this study were 3 male students aged between 19-23 years old, with average height and weight. All three of them have similar fitness conditions, because they are currently exercising by going to the gym or playing sports such as football. None of the participants mentioned any health problems or physical…

ground reaction impulses. In the most recent study from our lab we have shown that the activity of plantarflexors are modulated to change both the braking and the propulsive impulses (details at www). Visual perturbations were used in these experiments to elicit transient responses in muscles. It is not clear whether mechanical perturbations will result in the same changes during transient responses. Mechanical perturbations of walking surface can simulate natural conditions that result in…

Using kinematic equations, you will determine where a target will land. This experiment ignores air resistance. This projectile is launched with a speed of v(0) at an unknown angle. Therefore, the shape of the motion is predicted to be parabolic. Procedure The nerf gun is set up to a ring stand at approximately 50 cm above the table. Pick an unknown angle other than 0 or 90 degrees to launch the nerf bullet. Adjust the launcher so that it projects the projectile onto the table. For the first…

Have you ever wondered what it is like falling through the solar system? Well on this ride you will experience something very similar. You will pass each planet in the solar system while being forced up and over hills, loops, and turns. Riders will start on a hill reaching about 50 ft, reaching the most potential energy they will have on the entire ride. Following after that, they will plummet down the hill. As a consequence, they will experience the feeling of weightlessness, free fall, huge…

A ball, and a feather dropped at the same height will hit the ground at the same time when placed in a vacuum space. This is because acceleration of motion is the same for both object, and in this experiment, we are going to calculate accelerated motion using inclined planes. In this experiment, we will see whether “distance traveled is directly proportional to the square of the time”, and “if speed of a falling object depend only on the height from which it falls”. This experiment will give us…

(〖ms〗^(-1)) ∆ = change in h = height Kinetic Energy is the energy an object possesses due to motion. In layman’s terms, the greater the speed the greater the Kinetic Energy. Kinetic Energy is calculated by the formula: KE= 1/2 mv^2 Where: m= Mass (kg) v= Velocity (〖ms〗^(-1)) These different forms of energy are connected as when GPE is converted to Kinetic Energy is gained and vice versa. For example, when a ball is held in the air, it contains GPE based on its distance from the ground…

Wall-e is a new, dare say one of the best upcoming roller coasters and it is based off of the sensational movie Wall-e made by Disney’s Pixar! In the movie, the plot takes place in 2805 where humans have abandoned Earth on the account of it was not in the ideal shape for humankind to survive in. Therefore, humans left robots to clean up the mess they had made where after some time, the Earth became habitable once more. Mankind had been sending extraterrestrial vegetation evaluators or EVE to…

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…
