1
Q

Type of Motion: A______

Name and Explain

A

Angular

Motion occurring round a fixed point (axis of rotations)

2
Q

Type of Motion: L_____

Name and Explain

A

Linear

Motion occurs in a straight line

3
Q

Type of Motion: G______

Name and Explain

A

General

Combination of linear and angular

4
Q

Define motion

A

Continual change in position of the body

5
Q

Biomechanics: Balance

A

When the body is at a state of equilibrium and relies of supporting biomechanics to remain inside the base of support

6
Q

Biomechanics: Base of Support

A

Area beneath an object or person and is every point of contact

Biggest base of support: lying down on the floor

7
Q

Biomechanics: Transfer of Weight

A

Moving weight between body parts
Full weight transfer: walking, fruit-bat jump etc
Partial weight transfer: standing on one leg and then equalling the weight between two legs

8
Q

Biomechanics: Centre of Gravity

A

Weight is evenly distributed throughout the body, when the body transfers weight the centre of gravity moves

9
Q

Stability define

A

The ability to maintain balance

10
Q

Posture and body alignment

A

3 primary body weights - skull, thorax (ribs) and pelvis that are aligned over one another

Standing in parallel

Correct alignment means that the weight is carried in the bones rather than the muscles, decreasing the risk of injury.

11
Q

Newtons 1st Law

A

An object in motion stays in motion unless acted upon by another force.

12
Q

Newtons 2nd Law

A

The amount of acceleration when an unbalanced force acts on a body is proportional to the size of that force

13
Q

Newtons 3rd law

A

For every action there is an equal and opposition reaction
