Anatomy
The part of the skeleton consisting of the skull, vertebral column, ribs, sternum and coccyx. The axial skeleton is so named because it forms the long axis of the body.
What is the axial skeleton
A type of force that act on objects without coming into contact with them (e.g. gravitational force)
What is non-contact force.
A term used to describe the movement of any object that has been launched, hurled or thrown into the air
What is projectile motion.
The area beneath a person or thing that is in contact with a supporting surface
What is base of support.
A process in which the muscle lengthens to release the bones and move them further apart.
What is eccentric isotonic contraction.
A process during which the muscle (or muscles) on one side of a joint relax in order to accommodate the muscle (or muscles) on the other side of that joint that are contracting
What is reciprocal inhibition.
A unit of force equal to the force that would give a mass of one kilogram an acceleration of one metre per second
What is Newton (N)
A type of force that explains why objects that are spinning as they travel through the air curve away from the trajectory (i.e. pathway) they would ordinarily follow if they were not spinning.
What is magnus force.
The central point of an object, around which all of its weight is evenly distributed and balanced
What is centre of gravity.
A term used to describe the change in momentum that occurs over time when force is applied to an object
What is impulse.
A flexible but inelastic cord of strong fibrous collagen tissue attaching a muscle to a bone
What is a tendon.
A term used to describe the sequential combination of forces produced by different parts of the human body acting together to maximise force production
What is summation of force.
A fundamental law of the physical world; this law states that the force required to accelerate an object at a given rate is proportional to the product of that acceleration and the mass of the body; also referred to as the law of acceleration
What is newtons second law of motion- acceleration.
Levers that make it easier to move a heavy object with less force by increasing the distance over which the force is acting.
What is force multiplier.
A measure of how quickly or slowly the velocity of an object changes over time.
What is acceleration.
A lightweight mass filled with marrow, nerves and blood vessels; this forms the soft spongy centre of most bones
What is spongy bone.
A type of contact force that is generated by the surface of an object rubbing against the surface of another object
What is friction force.
Any movement that combines linear motion and angular motion.
What is general motion.
A type of lever in which the effort (i.e. force) is positioned between the load (i.e. resistance) and the pivot point (i.e. fulcrum)
What is third class lever.
An athlete throws the same object twice with the same force from a starting height of 1.6 metres.
Which component of projectile motion would have the greatest impact on the distances travelled.
What is height of release.
Bones that are small and develop in tendons where pressure develops.
What is a sesamoid bone.
A type of contact force that is generated by the resistance of an object to change shape
What is elastic force.
A term used to describe the tendency of a moving object to continue moving (in a straight line); the mass (e.g. in kilograms) of an object multiplied by its velocity (e.g. metres per second)
What is momentum.
A term used to describe the ability of a person or thing to maintain balance while moving (i.e. a gymnast performing on a jump a balance beam)
What is dynamic balance.
Two players collide with each other while moving at the same speed. Player 1 weighs 82 kg, while Player 2 weighs 74 kg. Determine which player will continue to move forward after contact and why (speed or momentum).
What is player 1 : momentum
