Q

Acceleration

A

A force applied to an object will produce change in motion

17
Q

Action & reaction

A

For every action their is a equal and oppose reaction

18
Q

1st class levers

A

The Axis is between the force and resistance

Eg: seashaw

19
Q

2nd class lever

A

The resistance is between the axis and force

Eg: wheelbarrow

20

3rd class levers

A

The force is between the axis and resistance

Eg: biceps

21
Q

Angular momentum

A

Involves rotation around a central axis or fixed point

22
Q

Impulse

A

Force applied to an object overtime

Force X time

23
Q

Summation of forces

A

The sequence of movement of each body segment to produce maximum velocity

24
Q

Friction

A

The resistance that one surface or object encounters when moving over another

25
Q

Movements

A

Adduction: body party moves towards midline of the body
Abduction: body part moves away from the midline of the body

Dorsi flexion: foot moves towards shin
Plantar flexion: foot moves away from shin

Inversion: soul of foot rolls inwards
Evervison: soul of foot rolls outwards
