Quiz #1 Flashcards
Use of the tools of mechanics and physics to study human motion
Biomechanics
The branch of applied mathematics dealing with motion and forces producing motion
Biomechanics
Explain how things in space and time by studying matter, forces and their effects

Types of biomechanical analysis:
- non-numeric
- direct visual observation
- video
- kinematic (temporal, spatial)
qualitative
Types of biomechanical analysis:
- kinematic (temporal,spatial)
- kinetic (force)
quantitative
Tools of mechanics
static and dynamic
Tools of mechanics:
- Objects at rest (a=0)
- Objects with constant speed (a=0)
static
Tools of mechanics:
- kinematics
- kinetics
dynamic
Tools of mechanics:
Static
- Objects at rest (a=0)
kinetics
Tools of mechanics:
Static
- Objects at a constant speed (a=0)
Kinematics and kinetics
Description of motion
- an examination of the effect of force
- analysis is temporal (time) and/or spatial (location)
kinematics
Useful for:
- comparing movements
- breaking skills down into manageable parts
- answering questions such as how fast, how high, how far
Kinematics
Quantifies:
Position, angle, distance, displacement, speed, velocity, acceleration, and momentum
kinematics
3 types of kinematics
- relative
- dependent
- general
3 types of general kinematics
- rectangular
- angular
- normal & tangential
2 subgroups of kinematics
- acceleration is constant
- acceleration is not constant
Defines and examines the forces that cause movement
kinetics
Useful for:
- directing, conditioning, training and rehabilitation programs
- identifying why injuries occur and how they can be prevented
kinetics
Quantifies:
inertia, mass, moment of inertia, force, weight, pressure, torque (moment), impulse, mechanical work, mechanical power
kinetics
Difficult to see and the analysis is considered to be difficult to do
kinetics
Anthropometrics - Newton’s law
impulse/movement - work/energy
linear (force) - angular (torque/moment)
kinetics
