Total questions: 20
Worksheet time: 8mins
Which of the following best defines a projectile in biomechanics?
An object that only travels in a straight line without spin
An object that remains on the ground until acted upon by a force
An object released into the air whose motion is influenced by gravity
An object that rotates around its own axis without changing position
What is angular motion?
Motion in a straight line
Motion around a joint or axis of rotation
Motion only affected by gravity
Motion with no spin
A tennis player applies topspin. What will the ball do?
Dip faster and bounce lower
Rise higher and bounce higher
Travel further in a straight line
Reduce air resistance
Which factor does gravity mainly affect in projectile motion?
Speed of release
Height of release
Mass of the object
Spin
If released at the same speed and angle, which will be slowed more by air resistance?
A basketball
A golf ball
A metal shot put
A dart
Which of the following best describes an open kinetic chain movement?
The end segment is fixed and immovable
The end segment is free to move through space
The end segment supports body weight
All body parts move together as one
What is an example of an open kinetic chain exercise?
Leg extension
Squat
Push-up
Leg Press
Which statement about force summation is most accurate?
It only involves the upper body
It is the process of combining forces from different body parts
It requires the smallest muscles to activate first
It is unrelated to coordination
In biomechanics, which muscles are typically activated first during force summation?
Smaller, faster muscles
Stabilising muscles
Larger, slower muscles
All muscles at once
Which of the following movements prioritises accuracy over velocity?
Javelin throw
Darts
Tennis serve
Baseball pitch
Which of the following is NOT a rule for velocity-dominant activities in force summation?
Use all body parts available
Use them in the correct order
Get the timing right
Keep all movements slow and controlled
Which of the following is NOT a rule for accuracy-dominant activities in force summation?
Reduce or control movement of redundant segments
Generate maximum endpoint velocity
Extend the body to reach the ideal position
Consistency in movement
What happens if the sequence of movements is performed out of order?
Maximum force is still generated
Accuracy always improves
Performance is reduced
The kinetic chain becomes closed
Which of the following best illustrates a closed kinetic chain exercise?
Bicep curl
Bench press
Push-up
Overarm throw
Which factor is most important for maximising accuracy in a closed kinetic chain skill?
Increasing distal segment velocity
Using only proximal segments
Minimising movement of unnecessary segments
Starting with distal-to-proximal sequencing
In the bowling sequence, what most logically follows the front foot plant?
Wrist release
Hip rotation
Finger release
Elbow extension
In velocity-dominant actions, a segment should be stabilised once it has acted.
True
False
The primary goal in throw-like activities is… (javelin, shot put, discus, hammer throw)
Consistency
Accuracy
End-point velocity
Balance
