biomechanics

Bones

________ and muscles work together to create movement.

Torque

________: the tendency of a force to cause a rotational movement around the axis.

Dynamics

________: study of systems that are in motion with acceleration.

Biomechanics

________: involves the study of how the body moves.

velocity

Kinematics: describing the characteristics in motion (displacement, ________, time, etc .)

human body

In the ________ there are three types of machines that provide movent.

Mechanics

________: the study of physical movement that results from forces.

Force

________ against a resistance causes the lever to rotate.

Mechanical advantage

________= force or resistance.

Kinetics

________: study of forces that are associated with movement of the human body.

Wheels

________ and Axles: used to enhance range of motion as well as speed of movement.

axis of rotation

Levers (most common): rigid bars that turn about a(n) ________.

Kinematics

________ and Kinetics: additional components in the field of biomechanics.

amount of force

Reduces the ________ needed to overcome a given resistance by enhancing the force.

Pulleys

________: a single pulley has a fixed axle.

→ mechanical advantage

________= radius of the wheel /radius of the axle.

great amount of force

A(n) ________ is required in order to move a relatively small amount of resistance.

range of motion

Increases the speed and /or distance of the given resistance enhancing ________.

mechanical advantage

The goal of the machine is to work in a cohesive unit to provide a(n) ________.

human body

The ________ acts as a machine.

Axis of rotation

________ is the same thing as a fulcrum.

Biomechanics

involves the study of how the body moves

Mechanics

the study of physical movement that results from forces

Statics

the study of systems that are in a consistent state of motion

Dynamics

study of systems that are in motion with acceleration

Kinematics and Kinetics

additional components in the field of biomechanics

kinematics

describing the characteristics in motion (displacement, velocity, time, etc.)

Kinetics

study of forces that are associated with movement of the human body

Levers (most common)

rigid bars that turn about an axis of rotation

Purpose

assist in balanced movements

Torque

the tendency of a force to cause a rotational movement around the axis

→ calculated as

force magnitude X force arm

→ resistance arm

distance between axis and point of resistance application

Wheels and Axles

used to enhance range of motion as well as speed of movement

Pulleys

a single pulley has a fixed axle
