DEFINITION : In physics, elasticity is the ability of a body to resist a distorting influence and to return to its original size and shape when that influence or force is removed. Solid objects will deform when adequate forces are applied to them. Mechanical Properties: Non-Linear Elasticity Mechanical Properties: Viscoelasticity There are three major characteristics…
Pulleys play a significant role in biomechanics, particularly in the context of human movement and the musculoskeletal system. They are mechanical devices consisting of a grooved wheel and a rope, cable, or belt that runs along the groove. Pulleys are designed to change the direction of a force and provide mechanical advantage, making it easier…
INTRODUCTION: A lever is a rigid bar that moves on a fixed point called the fulcrum when a force is applied to it. Movement is made possible in the human body by lever systems which are formed by our muscles and joints working together. An understanding of the lever systems in the body helps us…
What is a Gravity? DEFINATION: Gravity is a force that tries to pull two objects toward each other. Anything which has mass also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. Earth’s gravity is what keeps you on the ground and what causes objects to fall. Centre…
DEFINATION : Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. Friction is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding and rolling friction occur between…
Definition: force is the push or pulls on an object with mass that causes it to change velocity (to accelerate). Force represents a vector, which means it has both magnitude and direction. force An agent which produces or tends to produce, destroy, or tends to destroy the motion of a body is called force. ?…
DEFINATION: Motion is a movement that results from a force. In any physical activity, there are multiple forces and motions Occurring. motion as the change of position of an object with respect to time. A book falling off a table, water flowing from the tap, rattling windows, etc all exhibit motion. Even the air that…
In bio-mechanics, balance is an ability to maintain the line of gravity (vertical line from centre of mass) of a body within the base of support with minimal postural sway. Sway is the horizontal movement of the centre of gravity even when a person is standing still. A certain amount of sway is essential and…
1) DEFINATION : Biomechanics is the study of human motion. The study of biomechanics is important when determining what causes injuries and therefore how we can prevent them re-occurring. Physiotherapists are professionally trained to detect biomechanical faults which can predispose you to injury. 2) PRINCIPLES OF BIOMECHANICS Acceleration. the rate at which speed changes. agonist….
What is a Range of Motion(ROM)? Range of motion (ROM) is a measurement of the distance and direction a joint can move to its full potential. A joint is a location in the body where bones connect. Most of them are constructed to allow movement in predetermined directions. The amount of movement through a normal…
