What effect does the three point stance have on a football player’s stability?
It lowers the centre of mass, providing more stability.
This principle is crucial for maintaining balance during play.
How does a young T-ball player typically produce maximum force?
By standing upright, with feet planted, and swinging the bat using only the arms.
This technique can limit the effectiveness of the swing.
What does a proficient golfer rely on to produce maximum velocity?
A precisely sequenced swing, integrating leg, hip, and arm action.
This coordination helps achieve a controlled swing.
What is the impulse momentum principle in hitting?

This principle emphasizes the relationship between force and the resulting motion of the ball.
How does a soccer player change direction using force application?
By pushing their foot against the ground.
This action is essential for evading opponents.
What biomechanical principle is exemplified by throwing a curve in baseball?
Production of angular motion.
This principle is important for manipulating the ball’s trajectory.
What does conservation of angular momentum refer to in diving?
Divers in a state of free fall maintain their angular momentum.
This principle helps divers control their rotation during a dive.
