The problem this study is addressing is that in the physics classroom of a suburban high school, the teacher has access to enough laptop computers for every student to be able to use one, but does not use them because he does not know how to incorporate them into instruction or if they will be helpful in increasing learning. The purpose of this study is to find out if incorporating the laptops in a one to one computer based instruction will increase student achievement and motivation. The…

The purpose of this systemic review was to determine the level of evidence with hip strengthening or neuromuscular training and the effect on frontal plane knee kinematics and kinetics. Female athletes have a high risk of ACL injury. Athletes who are runners or play sports that involve running and jumping are at the highest risk for noncontact injuries. This is associated to the position of the knee during landing. Females typically land with a valgus force to the knee. This is a weak…

behind the biomechanical tenacity of movements and actions in order to identify any errors and the reasons behind the resulting mistakes in effort to make appropriate improvements. Two prerequisites are a crucial policy for diagnosing a motor skill, kinematics or technique exhibited by the performer and the performance outcome (Hall, 2014). Visual observation is the focal analytical element individuals drift towards to examine human…

on to program digital robots that navigated through a maze using Java language, designed and engineered a model bridge with Balsa wood, constructed and programmed vex machines to sort marbles based on weight, and built physics algorithms using Kinematic laws on Amazon hardware platform, molding technology and science. I can only imagine the exponential applications of such digitalization and the benefits of its…

The deadlift is one of the best compound movements used to strengthen leg, hip, back, and torso muscles. There are several variations of the deadlift, which are often utilized depending on the goals, needs, and abilities of the individual. This brief review will explore the different variations of the deadlift other than the standard conventional and sumo stance deadlift. The main variations used by powerlifters and regular gym goers are the conventional and sumo stance deadlifts. The main…

These cotters have a short threaded section at the narrower end of the taper, which is used to hold the cotter in place with a washer and nut. 2.1.4. Revolute Joint A revolute joint (also called pin joint or hinge joint) is a one-degree-of freedom kinematic pair used in mechanisms. Revolute joints provide single-axis rotation function used in many places such as door hinges, folding mechanisms, and other uni-axial rotation…

Model descriptions SWAN model The SWAN model [12,18] is based on the spectral action balance equation rather than the spectral energy balance equation. The evolution of the action density N is governed by Komen et al. [13]: ∂N/∂t+∇_x ⃗ ∙[((c_g ) ⃗+U ⃗ )N]+(∂c_θ N)/∂θ+(∂c_σ N)/∂σ=S_tot/σ where, N(σ.θ) is the action density spectrum, x is space, t is time,θ is wave direction, σ is relative frequency, S_tot is the source term total, and c_g represents the propagation velocity. The first term in the…

Introduction Functional electrical stimulation (FES) or neuromuscular electrical stimulation (NMES) is an therapeutic technique by which small electrical impulses are applied to a paralyzed or spastic muscle in order to induce contraction and thereby improve its function. Traditionally, NMES refers to those stimulatory protocols directed at increasing strength and FES with function. FES can stimulate muscle contraction for exercise, bladder management, grasping, standing, and walking, among…

The effects of technology and pressure are crucial in the determination of principles of the space shuttle tires. The physics formula of air pressure, desired revolutions of the tire over a distance is determined. The equations of the rotational kinematics and the dynamics are very useful in the determination of the landing speeds of the space…

There is an alteration in breathing and kinematics of the diaphragm in our clients with this pain (Roussel, Nijs, Truijen, Smeuninx & Stassijns, 2007). Thus it is important that we manage SM’s chronic pain in order to promote easier oxygenation. 5) Breathing techniques are used to support clients…
