Evaluate the strengths and weaknesses of your chosen skill.
Look at 3 biomechanical principles
Task 2
Stability / Projectile Motion / Force Summation / Levers /
Newton’s LawsStrengths
Weaknesses
Watch this you Tube of a tennis serve
• What are the strengths– Wide base of support– Good force summation
• What are the weaknesses• Newton’s 2nd Law• Projectile Motion
Strengths
• Look at your initial performance • What did you do well• What was successful for you
Weaknesses
• What went wrong• What can you focus on for your practice
sessions• This is what your practice sessions should be
focused on.
Words that you might use for the biomechanical term Stability
• Centre of gravity• Base of support• Balance• Line of gravity• Stability• Principle #3 page 64• Principle #4 page 64
Force summation
• Sequencing of body segments• Generate maximum momentum• Large muscle groups• Small muscle groups• Stretching out• Full range of motion
Projectile Motion
• Speed of release• Projectile• Angle of release• Optimum angle is 45° is this what you want
for your skill though??? Think what would be best for your skill. Quest 4 page 78
• Height of release
Newton’s Laws1st law force
2nd law direction
3rd law Equal and opposite
mass Reaction force
inertia Initial force
acceleration increases
Levers
• 3rd class levers• Longer the lever• Wide range of motion• More velocity / speed• Strike• Generate
