This online resource discusse the mechanical principles applied to sports as rules that govern the efficient execution of skills. Using these rules as guides, athletes can build excellent technique and gain the greatest mechanical advantage. Newton's Laws of Motion are the foundation for these mechanical principles, which must be applied in concert with other sports training principles to achieve higher levels of sport performance.

Newton's laws of motion form the basis for principles used in sport movements. Methods of training that depart from these laws would not make sense mechanically. Tips for efficient sport performances are built around these laws and principles.

Projectiles in sports include objects and athletes in flight as a result of throwing, batting, kicking, and jumping. Principles about the effects of force concern angle, height, impact, and spin on sport objects. Understanding these effects offers direction for developing sound technique for related sport skills.

Force is the product of the mass (weight) and acceleration of an object or person. Principles of force offer guidance for teaching sport techniques and leveraging training strategies that require the development of force--pushing or pulling. These principles and examples concern (a) general applications, (b) athlete-produced force, and (c) force dissipation.

Stability principles give athletes rules about holding positions and staying on balance when running. They guide training for improving firmness of positions both for static balance and dynamic balance.
