Physical Education Units 3, 4 - Biomechanics

Define biomechanics

• The study of the mechanical principles that govern movement

• The study of forces that cause motion and result from motion

• The study of movement with reference to time, distance, displacement and velocity

• A body/objects change in position in relation to time

Define Kinetics

• The study of the mechanical principles that govern movement

• The study of forces that cause motion and result from motion

• The study of movement with reference to time, distance, displacement and velocity

• A body/objects change in position in relation to time

Define Kinematics

• The study of the mechanical principles that govern movement

• The study of forces that cause motion and result from motion

Define Motion

• The study of the mechanical principles that govern movement

• The study of forces that cause motion and result from motion

• The study of movement with reference to time, distance, displacement and velocity

What do biomechanics principles contribute to

• explanation of moement

• description of movement

• prediction of movement

• repetition of movement

Define Linear Motion

• motion that occurs in a straight line or curved path

• Motion the occurs when a body/object moves in a circular path

• a combination of linear and angular motion

• translation

• rotation

Define Angular Motion

• motion that occurs in a straight line or curved path

• Motion the occurs when a body/object moves in a circular path

• a combination of linear and angular motion

• translation

• rotation

Which apply to general motion

• motion that occurs in a straight line or curved path

• Motion the occurs when a body/object moves in a circular path

• a combination of linear and angular motion

• A sprinter running in a straight line

• rotation

Define force

• The quantity of matter found within a particular body

• The resistance of a body/object to change its state of motion

• An effect on one body that results from the interaction of a second body

• the product of mass and acceleration
