BALANCE & STABILITY
What is balance/stability?
This is the ability to maintain equilibrium while stationary or moving.
What is number is Law of Inertia?
Newton’s First Law is also known as this law.
These are the three factors of projectile motion.
angle, speed, and height of release?
This biomechanical principle involves using body parts sequentially to generate maximum force.
summation of momentum/force
Explain the difference between “describe” and “analyse.”
Describe = state features; Analyse = break apart and explain relationships. WHAT HOW WHY
A soccer goalkeeper widens their base before diving. Explain why this improves stability.
Wider base increases stability.
Explain how Newton’s Second Law affects the force of a soccer kick.
Greater force = greater acceleration.
Explain how speed of release affects a soccer shot.
Greater speed usually increases distance/power.
Explain how follow-through improves accuracy in soccer passing.
Follow-through keeps movement controlled and directed and impulse can increase force applied
Evaluate why biomechanics and functional anatomy is important?
Teacher discretion
Analyse how lowering the centre of gravity helps a touch football player evade defenders.
Lower centre of gravity improves control/change of direction.
Analyse how Newton’s Third Law occurs when sprinting in touch football.
Push against ground → ground reaction force pushes athlete forward.
Analyse how angle of release changes the flight path of a soccer chip kick.400
Higher angle increases height/time in air. 45-50degrees optimal for longer distance, low angle=fast
Analyse how summation of momentum can increase force in a touch football pass.
Sequential body movement increases force transfer.
A movement strategy is and justify two examples to improve a goal kick and touch footy pass
Evaluate the importance of balance and stability when kicking a soccer ball accurately under pressure.
Improves accuracy, control, force transfer, injury prevention.
Evaluate which Newton’s Law is most important for acceleration in soccer. Justify your response.
Usually Second Law because force affects acceleration.
Analyse the effect of contact forces on a soccer ball during a curved free kick.
Contact force from foot creates spin/force affecting trajectory.
Drag force
Bernoulli's principla
Evaluate one movement strategy a soccer player could use to improve shooting accuracy.
Stable base, eye on ball, correct body positioning etc.
Teacher discretion
Compare the movement strategies used to maintain stability in a soccer tackle and a touch football sidestep.
A player slows down suddenly while defending in touch football. Explain how inertia affects their movement and performance.
Body continues moving due to inertia; harder to stop/change direction.
Compare the importance of drag force and gravity during a long touch football pass.
A player generates powerful kicks but poor accuracy. Evaluate two biomechanical adjustments they could make.
Improve balance, plant foot position, follow-through, body alignment.
