thrown objects using Photogate Tape (ME-6664), a Photogate (ME-9204B)
and a Digital Adapter (PS-2159).
Collect data from two or more joints simultaneously while walking,
running, jumping, throwing, kicking, etc. How do the joints work together
when performing these actions?
Oscillations
Collect data for the following:
• Lower leg freely dangling about the knee showing simple harmonic
motion, subject seated on a high surface.
• Leg with unbent knee freely dangling about the hip, subject standing on
the opposite foot on a low surface.
• Leg with knee bent at right angle freely dangling about the hip.
Do angle, angular velocity, and angular acceleration approximate simple
harmonic motion? Determine the period, frequency and amplitude of the
oscillations.
What is the relationship between the phases of angle, angular velocity, and
angular acceleration?
How does bending the knee affect the frequency of the dangling leg?
Skeletal Parts
Mount the Goniometer on articulated skeletal parts. In conjunction with
force sensors attached with string the points of tendon attachment, measure
the forces exerted by muscles when lifting objects of various mass, or
performing throwing and kicking movements.
