Biomechanics of the Body DVD

The physics of human movement - suitable for GCSE and AS students

This DVD set complete with teachers guide and photocopiable diagrams looks at the physics of human movement, and shows how it can be used to optimize athletes' performance.

It deals with:

• Forces - Newton's Three Laws of Motion
• four different types of forces: isometric, isotonic, sub-maximal, maximal
• five main principles for applying force at maximum efficiency: inertia, momentum, impulse, accuracy, force reception
• Levers - three components: force arm, fulcrum and resistance arm
• three types of levers - first, second and third class levers
• examples of each within human body and external to the body
• Motion - linear, angular and general motion
• moment of inertia, angular momentum, projectile motion dependent on height and angle of release, and object's weight and shape
• projectile motion also affected by air resistance and spin
• Friction - rolling and sliding friction
• manipulating friction by altering surfaces or forces
• Balance and stability - stability dependent on line of gravity, weight of object and position of base of support
• centre of gravity and line of gravity; static and dynamic stability.
