The document discusses several key mechanical principles:
- Resistance can help or hinder depending on the situation. It slows swimmers but helps slow runners at the end of a sprint.
- Transferring weight is important for movement and generating power in activities like badminton and discus throw.
- Propulsion in water sports like swimming comes from using arms and legs as levers to push against the water.
- Force and friction can be advantageous or disadvantageous depending on the activity and situation.
- Centre of gravity determines balance - it must stay within the base of support for stability.
- Levers in the body allow for speed or control depending on their length.
- Streamlining reduces resistance by making
