Angular Kinematics
The SI units for angular velocity
radians/sec
The equation for torque
T=F*d
Law that describes bone adaptation to stress
Wolff’s Law
Law that describes muscle adaptation in response to stress
Davis’ Law
Functional unit of the nervous system
Neuron
Ways to manipulate angular acceleration (two variables)
velocity and time
A lever that has the load between the fulcrum and the effort
second
Organic material of bone
protein (collagen)
Type of contraction that produces the most force
Eccentric
Type of neuron that carries info from CNS to muscles
efferent
The difference between angular distance and displacement
distance= total, displacement= final - initial
This is required to cause a change in angular momentum
angular impulse
Type of bone that can handle stress better than strain
Compact
Increase in CSA of muscle
Hypertrophy
The principle that small motor units get recruited first
Henneman’s principle
The relationship between linear and angular velocity (equation)
v=r*w
This is conserved when a figure skater pulls their arms in to spin faster
angular momentum
An exercise that increases bone mineral density in legs
Load-bearing (e.g. walking, running)
What parallel muscles are better at than pennate muscles
range of motion/shortening velocity
The sensory receptor that detects muscle length
muscle spindle
When a wheel has a larger radius, linear velocity ___ at the same angular speed
Increases
If torque increases, and moment of inertia remains the same, then angular acceleration ____
increases
The point on a stress-strain curve where an object cannot go back to its original shape
Yield point
Fiber type that decreases in older adults
Type 2
The type of coordination that improves movement efficiency between muscles
intermuscular
