stability |
resistance to disturbance of balance |
|
|
capacity of an object to return to equilibrium or its original place after being displaced is also known as |
stability |
|
|
the ability to control the forces that make an athlete stable |
balance |
|
|
what controls stability |
balance |
|
|
to increase stability one must |
increase mass increase inertia |
|
|
____________ force is important in stability especially when mass is larger |
frictional force |
|
|
what is the resistance of an athlete against being moved or spun around in any direction |
rotary stability |
|
|
true or false athletes with little rotary stability can resist the destablization and torque applied against them |
false. great rotary stability
|
|
|
name some sources than can create destabilizing troque |
gravity air resistance an opponent |
|
|
stability determining factors |
base of support central line of gravity within base of support center of gravity ( lower the better) body mass (greater inertia) extension of base in direction of oncoming force shift line of gravity towards line of force |
|
|
what is the area on ground enclosed by points of contact with the athletes body |
base of support |
|
|
true or false the base of support is always below athlete
|
false. anything that provides resistance against forces exerted by the athlete can become a base |
|
|
___________ base of support = ____________ stability |
larger, greater |
|
|
what is a key factor for base of support |
frictional resistance between ground and contact points |
|
|
what is the location of the central line of gravity |
vertical projection from the cog to the ground within base of support |
|
|
stability while moving is known as |
dynamic stability |
|
|
___________ COG= __________ stability |
lower, increased |
|
|
true or false. decrease body mass = increased stability |
false. increase |
