- What is Kinesiology? Kinesiology is the science focused on the study of motion
- What is biomechanics in terms of kinesiology? Biomechanics is one of the core courses in kinesiology and contributes to a basic understanding of human movement possibilities; other core courses: anatomy and physiology, psychology of sport and exercise, excercise physiology, and motor learning
- What is mechanics? Mechanis is physics and focuses on the effect of forces. A force is basically a push or pull applied to a body. The term "body" is used to focus on an important area during analysis (a body can also be an individual segment).
- What are Rigid body mechanics? Rigid body mechanics: - an applied force affects the motion of a body (body speeds up or slow down) - modeled as a single, rigid bar
- What is fluid mechanics? Fluid mechanics: forces applied to a bodymoving in air or water (lift and drag)
- How many and which branches does biomechanics use, along with the structure and function of the living body, to explain how and why bodies move as they do? There are three branches of mechanics: Rigid body mechanics, Fluid mechanics and Deformable body mechanics
- What is Deformable body mechanics? Deformable body mechanics: - focuses on the changes in the shape of the body - an applied force causes a deformation by loading the particles of material making up the body - the loading applied to a body is called stress - size and direction of the stress cause deformations called strain - understanding the relationship between stress and strain is important to train impaired tissue
- What means the "Bio" in biomechanics? Bio is greek for life, making biomechanics the science applying the principles of meachenics to aliving body. Biomechanics is used to study and explaij how and why living things move as they do. The following systems are important to the mechanics of movement: Skeletal system: inclusing bones, ligaments, and joints, provides the physical structure of the body and alllows for movement Neural system: also known as the nervous system, including different type types of nerve cells, serves as the communication system to control and respond to movement Muscular system: including muscle and the tendon attaching muscle to bone, provides the motors we control to make the body move
- What are the two subdivisions of each branch (Rigid body mechanics, Fluid mechanics and Deformable body mechanics) of mechanics? Two subdivisions: Kinematics (motion) and kinetics (forces that cause motion) Kinematics: subdivision between Linear and Angular, considering position, velocity and acceleration Kinetics: subdivision between Linear (Force) and Angular (Torque)
- What is kinematics? Kinematics is the subdivision of mechanics focused on the description of motion, what we see happen to the body. A kinematics analysis considers the position of a body, how far it travels, how fast it travels and whether it's speeding up or slowing down.
- What is general motion? General motion describes coordinating multiple segments at multiple joints to create linear motion of one part of the body. Most human movement is general motion.
- What is Linear kinematics? Linear kinematics describes linear motion, or motion along a line (also called translation). There are two forms of linear motion: Rectilinear motion: Translation in a straight line. Your fingertip exhibited rectilinear motion as you succesfully traced a line across the page. Curvilinear motion: Translation along a curved line. Your fingertip exhibited curvilinear motion when you tried to move it across the page using only a single joint. Curvilinear motion also describes the path followed by an object moving through the air without support, like a thrown ball or a jumping child. This airborne body is called a projectile, and the curvilinear path it follows is called a parabola (an inverted U-shaped path).
