In sport performance analysis, modern technology can generate numerical data as well as movement‑quality information. Can these tools be used to deliver both quantitative and qualitative evaluations of an athlete’s technique?

No, technologies only provide quantitative measures.

Not sure.

Yes, technologies can be used for both quantitative and qualitative assessment.

No, technologies only provide qualitative measures.

yes, technologies can be used for both quantitative and qualitative assessment

A coach films a wrestler performing a maximal‑effort front crawl and wants to evaluate how the wrestler’s elbow is positioned relative to the hand during the pull phase. What type of analysis does this evaluation represent?

can be all of the above type of analysis

kinetic analysis

kinematic analysis

quantitative analysis

kinematic analysis

Match the scenario with the correct law.

A basketball stays still until a player dribbles or shoots it. When airborne, the ball continues its path until gravity, air resistance, or the hoop alters its motion.

 

When a player shoots the ball, the force exerted by their legs and arms propels the ball upward. The greater the force applied, the higher the ball travels towards the hoop.

 

When a player kicks the ball, their foot exerts a force on the ball, and the ball exerts an equal and opposite force back on the player's foot. This interaction propels the ball forward.
