Simple Mechanics of Motion

Mechanics is the area concerned with the motion of physical objects. Forces applied to objects result in displacement or changes of an object position relative to its environment.

Mechanics may be divided into three branches:

      1.     Statics: It deals with forces acting on and in a body at rest.

      2.     Kinematics: It describes the possible motion of a body or system of bodies

 3.Kinetics: This attempt to explain or predict the motion that will occur in a given         situation

Principles of lever system

The lever is a simple machine that changes the magnitude and detection of the force applied to move an object. It minimizes the effort required to lift the object. A lever is a rigid bar that moves around a supporting point (pivot or fulcrum). The object to be lifted is placed on the bar.

Gravity: It is a universal force of attraction acting between all matter

Velocity is the speed at which something moves in one direction. 

Balance: This is a situation in which different elements are equal or in correct proportion

Application of Mechanics to Game Situation

A game mechanics are the rules and procedures that guide the player and the game response to the player’s moves or actions.

      1.     It helps in reducing or minimizing the risk of injury.

      2.     It improved sport performances

      3.     It helps analysis and assessment of human movement during sport activities

      4.     It helps to describe motion or movement and how forces is created

      5.     It helps in describing how and why human body moves in the way it does

     6.     It helps to consider the interaction between the performer, equipment and                  environment

      7.     It improves muscular skill

      8.     It improves physiological capacities and psychological or cognitive abilities

      9.     It helps in the identification of optimal technique for enhancing sports performances

10.The analysis of body loading to determine the safest method for performing a       particular sport or exercise task


Assignment

Revise, study and prepare for the coming SSCE exam.

PHYSICAL EDUCATION E-CLASS     COORDINATED BY MRS BLESSING TITILOYE TOPIC FOR TODAY TYPES OF CROUCH START IN SPRINT RACES *This material is specifically prepared for SS3 students preparing for WASSCE Crouch start There are basically two ways of starting races in athletics. They are namely standing start and crouch start but today we are focusing on crouch start. There are three main types of crouch start in sprint races which are:   Ø Bunch or bullet   Ø Medium   Ø Elongated The difference between these starting positions is found during the "on your marks" part of the start. The "On your marks" part of the race is when sprinters are in the starting blocks and they are in their very first phase of the start. The hands of the sprinter are shoulder-width apart, their knees are bent with the knee of the back leg on the ground and their feet are on the starting blocks. The start has three phases: on your marks, get set, then
