QuestionAnswer
What does anterior mean? Towards the front
What does Posterior mean? Towards the back
What does Superior mean? Towards the head
What does Inferior mean? Toward the feet
What does Medial mean? Toward or at the midline of the body
What does Lateral mean? Away from the midline of the body
What does Proximal mean? Located nearer to a point of reference
What does Distal mean? Located further from a point of reference
What does Flexion mean? Away movement that decreases the angle of the joint
What does Extension mean? Any movement that increase the angle of the joint
What does Abduction mean? Movement of a limb away from the body
What does Adduction mean? Movement of a limb towards the body
What does Rotation mean? Movement of a bone around its longitude axis without lateral or medial displacement, such as shaking the head
What does Circumduction mean? Combination of flexion, abduction, extension and adduction performed one after the other
What does Supination mean? Movement so the radius and ulna at the elbow so that the palm is up
What does Pronation mean? Movement so the radius and ulna at the elbow, so the palm is down
What does Inversion mean? Movement of the sole of the foot inwards
What does Eversion mean? Movement of the sole of the foot outwards
What is Kinematics? Motion of a body
Three types of motion? Linear motion, Angular motion, General motion
Define linear motion? Motion of a body in a straight line
Define angular motion? Motions of all parts of the object move around a fixed point.
Define general motion? Combination of linear and angular. e.g. Swimming.
Which type of motion can be internal and external? Angular motion, eg internal: Shoulder Joint, External: Eneven Bars
What is projectile motion? Object which moves through the air
What are the factors affecting projectile motion? (6) Velocity at release, Angle of release, Height of release, Shape, Air Resistance and Spin
Give an example of an object which would have a angle of release over 45 degrees and one below 45 degrees? U: Bowl in cricket H: Netball shot
Briefly explain velocity at release? The harder a ball is hit or thrown the higher and further it'll travel
Briefly explain angle of release? Angle of release depends of the shape and aerodynamic properties of the projectile
Briefly explain height of release? Higher the point of release relative to the ground the further the projectile will follow
Briefly explain what the shape has to do with projectile motion? Streamlined shapes travel more effectively in the air due to less drag force
What is Air Resistance? When a projectile pushes through the air it creates a drag force behind it
What is Kinetics? Forces associated with motion
Define mass and what it is measured in? Amount of matter that makes up an object, measured in KG
Define force? and what is it measured in? Is the push or pull on a body that can possibly cause change, me
Two types of forces? From within the body by muscular contractions, With an aid of equipment
Newtons first law of motion? A body continues in it's state of rest or state of motion unless acted upon by a force
Force can achieve what? Acceleration, Deceleration, Stop, Start, Change shape, Change Direction
Newtons second law of motion? Force = mass x acceleration
Newtons third law of motion? For every action there will be an equal and opposite reaction
What acts as leavers and what acts as axis? Bones act as leavers while joints act as axis
Define Stability? The body's ability to remain in a state of balance, stability can be static or dynamic.
Why do we analyse performance? (3) Ensure the correct techniques are being used Identify Errors Justify the suggested changes in technique that are recommended
How many steps are there in biomechanical analysis? 6

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
