Name one example of a first-class, second-class and third-class lever system in the human body.
First-class lever: fulcrum in the middle (nodding the head). Second-class lever: load in the middle (a calf raise). Third-class lever: effort in the middle (a bicep curl) — the most common type in the body.

Selective attention.
What term describes the difference between oxygen supplied and oxygen required at the start of exercise, and what term describes the extra oxygen consumed after exercise ends?

Answers:
During a somersault, a diver pulls their arms and legs into a tight tuck position. Using the concepts of moment of inertia and angular velocity, explain why this makes them spin faster.
Tucking in brings the body mass closer to the axis of rotation, which decreases moment of inertia. Since angular momentum stays constant (conservation of angular momentum), a decrease in moment of inertia causes an increase in angular velocity — so the diver spins faster.
Explain Bernoulli's principle and how it causes a spinning ball to curve in flight.
Faster-moving air = lower pressure; slower-moving air = higher pressure. Spin makes air move faster on one side of the ball than the other, creating a pressure difference — the ball curves toward the low-pressure side.
Which approach to motor learning explains skill development through the interaction of performer, task and environment, rather than fixed mental instructions?
