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
