A level PE - analysis using technology test questions with passed
solution
1. limb kinematics study of movement in relation to time and space which produces a
digital format of the joints and limbs
2. how does limb computer software is linked to cameras which convert the motion shown
kinematics by reflective markers into a digital format
work?
-immediate and highly accurate
3. pros of limb -can focus on a specific limb/piece of equipment
kine- matics -can analyse preparation, execution and recovery
4. cons of limb kine- - repeatability and accuracy is dependant on the placement of
markers
matic -expensive
s -limited to laboratory conditions
5. force plates measure the ground reaction forces generated by a body standing on
or moving across them and are used to quantify balance and gait
6. how do when an object makes contact, an electrical output proportional to
force the force is displayed on a computer in the form of a graph
plates
work? -immediate, accurate and reliable results
-can analyse performance and health
7. pros of
force -specialist and expensive
plates -laboratory conditions may force a performer to adapt their
performance limiting potential use
8. cons of
force
plates
9. wind tunnels used to study the flow of air around an object and smoke or dye may
be used for this
10. how do wind tun- nels work?
