Stability - n
ANS ✔
A person is more or less stable depending on the area of their supporting base
Qs
Acceleration - n
ANS ✔
The rate of change in velocity over a certain period of time
Qs
Torque - n
ANS ✔
The force that causes something to rotate
Qs
Force - n
ANS ✔
The push or pull exerted on an object
Qs
Mass - n
ANS ✔
The quantity of matter in an object
Qs
Center of Gravity (COG) - n
,ANS ✔
AKA Center of Mass
More Stability= lower center of gravity
For Max stability= COG is perpendicular to the ground and the center of the base
Movement requires you to change your center of gravity
Qs
Friction - n
ANS ✔
The force created by an object's contact with the ground.
Depends on
1) Weight of the Object
2) Surface of the ground
Qs
Tonic Neck Response - n
ANS ✔
Movement in relation to the neck and limbs
Qs
Centripetal Force - n
ANS ✔
The force exerted on an object moving in a circle
Qs
Inertia - n
ANS ✔
, Any object's resistance to a change in velocity
Qs
Weight - n
ANS ✔
Mass x Gravitational Constant
Will vary depending on the gravitational force
Qs
Momentum - n
ANS ✔
The tendency of an object in motion to stay moving
Mo= velocity x mass
Objects with the same speed will have different momentum if the masses are
different
Qs
velocity - n
ANS ✔
The measure of speed and direction of an object
Velocity= distance/time or Final Distance- Initial Distance/Time
Qs
After- Contraction Phenomenon - n
ANS ✔
The increase in the force of movement that seems to happen when the
neuromuscular systems become excited
