What are the three key factors that determine the trajectory of a projectile?
Speed of release, height of release, and angle of release.
What is the optimal release angle for most throwing sports?
Between 35-42 degrees due to air resistance.
What do steep lines on a velocity-time graph indicate?
Rapid acceleration.
What does a flat line on a distance-time graph represent?
Constant velocity.
What does the area under a force-time graph represent?
Impulse, which is crucial for understanding momentum changes.
What is the center of mass (COM) in relation to body movement?
The point where the mass of the body is concentrated, which can change position during movement.
How does the COM behave during running?
The COM stays within the body.
What happens to angular momentum when an athlete tucks their arms in during a spin?
Decreased moment of inertia leads to increased rotation speed.
What is the formula for angular momentum?
where I is moment of inertia and ω is angular velocity.
What are free-body diagrams used for in sports analysis?
To show forces acting on an athlete, such as gravity and ground reaction forces.
What modern tools are used for performance analysis in sports?
High-speed video analysis, force plate measurements, and motion capture systems.
What is the significance of understanding movement analysis principles?
It helps coaches and athletes optimize technique and prevent injuries.
What does a negative slope on a velocity-time graph indicate?
Deceleration.
What is the effect of arm position on rotation speed in diving?
Tucked position results in faster rotation, while extended position results in slower rotation.
What is the relationship between moment of inertia and rotation speed?
Increased moment of inertia decreases rotation speed, and vice versa.
What is the primary focus when analyzing sports movements?
Identifying the primary forces involved and their directions.
What can athletes and coaches achieve through systematic movement analysis?
Identify technical flaws, optimize performance, develop effective training programs, and reduce injury risk.
