Biomechanics

Question 1

Projectiles

Answer 1

Any object in flight
Usually follow parabolic flight path
Which means flight path is symmetrical

Question 2

Parabolic flight path means

Answer 2

Flight path is symmetrical

Question 3

Factors affecting projectiles

Answer 3

Force of release
Height of release
Angle of release

Question 4

Force of release

Answer 4

More force projectile released, further horizontal distance

Question 5

Height of release

Answer 5

Higher the projectile is released, further the horizontal distance

Question 6

Angle of release

Answer 6

The closer to 45 degrees the projectile is released, further horizontal distance will be

Question 7

Shot putt

Answer 7

• Parabolic
• Gravity acts on vertical component
• Mass of shot (mass x gravity) weight dominant force
• Air resistance negligible
• Speed is slower

Question 8

Shuttlecock

Answer 8

• Not follow parabolic
• Air resistance acts on vertical component
• Shape of shuttle air resistance dominant force
• Weight negligible
• Speed quicker

Question 9

Sagittal plane (line down middle)

Answer 9

Transverse axis
- forward/backward
-upward/downward
- flexion/ extension

Question 10

Frontal plane (line down side)

Answer 10

Sagittal axis
- Abduction/Adduction

Question 11

Transverse plane (line across waist)

Answer 11

Longitudinal axis
Horizontal Abduction/Adduction

Question 12

Where is sagittal plane split

Answer 12

Down middle

Question 13

Where is frontal plane split

Answer 13

Down side

Question 14

Where is transverse split

Answer 14

Across waist
