Biomechanics

Question 1

Force

Answer 1

Mass x acceleration (N)

Push or pull that alters the state of motion

Question 2

Velocity

Answer 2

Displacement/time (m/s)

Rate of change of displacement

Question 3

Weight

Answer 3

Mass x acceleration from gravity 9.81 (N)

The gravitational pull on the body

Question 4

Momentum

Answer 4

Mass x velocity (kgm/s)

Quantity of motion passed by a moving body

Question 5

Acceleration

Answer 5

Final velocity-initial velocity/t (m/s/s)

Question 6

N1 inertia

Answer 6

An object will remain at rest or in constant motion until acted upon by an external force

Question 7

N2 acceleration

Answer 7

The rate of change of momentum is proportional to the force applied and acts in the direction

Question 8

N3 reaction

Answer 8

For every action, there is an equal and opposite reaction

Question 9

Limb kinematics

Answer 9

The study of movement in relation to time & space

Question 10

Pros of Limb kinematics

Answer 10

-Data is: immediate, objective, accurate
-Analyses technique and can improve performance
-Focus can be placed on limb or equipment

Question 11

Cons of limb kinematics

Answer 11

-Accuracy depends on the placement of limb markers
-Technique is highly specific
-Equipment is expensive
