The document provides an overview of mechanics of movement in sports. It discusses key concepts like vectors and scalars, velocity, acceleration, momentum, and how Newton's Laws of motion apply to athletic movements and the application of forces. Examples are provided for calculating speed and velocity. Graphs demonstrate changes in velocity over time and how this relates to acceleration. Forces acting on athletes in different sports are identified and explained in relation to Newton's Laws.

15. Velocity/time graphs Velocity Time Velocity changes

17. Velocity Time On a velocity-time graph acceleration is shown by the of the line steepness (gradient)

18. Velocity Time Highest acceleration? zero acceleration? deceleration?
