The document discusses key concepts in biomechanics including: - Characteristics of linear, angular, and general motion. - Centre of gravity and how it can change depending on body position. - Line of gravity and base of support in relation to stability. - Newton's laws of motion and how they apply to human movement. - Force summation and how multiple body parts can work together to maximize force. - Projectile motion principles like gravity, speed, height, and angle of release that influence how objects are thrown or projected.
