Stability - Answers -A person is more or less stable depending on the area of their
supporting base
Acceleration - Answers -The rate of change in velocity over a certain period of time
Torque - Answers -The force that causes something to rotate
Force - Answers -The push or pull exerted on an object
Mass - Answers -The quantity of matter in an object
Center of Gravity (COG) - Answers -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
Friction - Answers -The force created by an object's contact with the ground.
Depends on
1) Weight of the Object
2) Surface of the ground
Tonic Neck Response - Answers -Movement in relation to the neck and limbs
Centripetal Force - Answers -The force exerted on an object moving in a circle
Inertia - Answers -Any object's resistance to a change in velocity
Weight - Answers -Mass x Gravitational Constant
Will vary depending on the gravitational force
Momentum - Answers -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
velocity - Answers -The measure of speed and direction of an object
Velocity= distance/time or Final Distance- Initial Distance/Time
, After- Contraction Phenomenon - Answers -The increase in the force of movement that
seems to happen when the neuromuscular systems become excited
eg. Pressing against a wall for a minute
Flexibility - Answers -The range of motion around particular joints
Increases strength
Dynamic Resistance - Answers -Exercising close to the maximum level of resistance
Creates the most strength
Muscle Strength - Answers -The ability of the muscles to exert force
Muscle Endurance - Answers -The ability to continue performing any muscle activity
despite fatigue in a specific muscle
Different Types of Strength - Answers -1. Dynamic Strength
2. Isotonic Strength
3. Static Strength
Strength - Answers -The ability to create force or exert force
Dynamic Strength - Answers -Movement in which several different muscles are involved
in a series of contractions.
eg. Lifting an object above your head
Isotonic Strength - Answers -When the length of the muscle changes, the tension of the
muscles stay the same.
Static Strength - Answers -Exerting force on an object without any movement from the
object
Muscular Power - Answers -The muscle's ability to exert force over a period of time
or
The Degree of explosiveness a muscle can exert
Muscular Endurance (2) - Answers -The ability to continue performing any muscle
activity despite being fatigue
Overload Weight Principle
(Principles of Strength training) - Answers -The best way to build muscle strength is to
train at the max level of resistance
