- - - - Linear motion occurs when all parts of a body move in the same direction at the same speed, along a straight or curved path. In the triple jump, the athlete’s body moves through a sequence of hops, steps, and jumps, following a generally straight or slightly curved path down the runway and through the air 1234.
    - - The athlete applies force against the ground during the run-up and each phase of the jump. This force propels the body forward and upward, altering the state of motion. The greater the force applied (especially during take-off), the greater the acceleration and distance achieved 134.
    - - Speed is the distance covered over time, while velocity includes direction. In the triple jump, maintaining high speed during the approach and efficiently converting horizontal velocity into vertical lift at take-off is crucial for maximizing distance. The athlete’s velocity at take-off determines the effectiveness of each jump phase 14.
    - - Momentum (mass x velocity) is key in the triple jump. The athlete aims to maximize momentum during the run-up and maintain it through each phase. Greater momentum allows for longer jumps, but the athlete must control and transfer this momentum efficiently from the hop to the step and then to the jump 1214.
    - - Impulse is the change in momentum, calculated as force x time. In the triple jump, the athlete increases impulse by applying force over a longer period during take-off, which helps generate greater momentum and distance. Proper technique in each phase ensures the force is applied effectively 124.
    - - The athlete uses as many body parts as possible in a coordinated sequence, starting with larger muscle groups and moving to smaller ones, to generate maximum force and velocity. Correct timing, stabilization, and follow-through in each phase are essential for optimal performance
  - - - Definition: Linear motion occurs when all parts of a body move in the same direction at the same speed, along a straight or curved path. In the 1500m run, the athlete's body moves along the curved track, with all body parts moving in the same direction and speed during each stride 1234.
    - - Definition: A force is a push or pull that alters the state of motion of a body. In running, the force is generated by the contraction of skeletal muscles, propelling the runner forward.
      - Application: The runner applies force to the ground with each stride, which accelerates the body forward. External forces such as gravity, friction, and air resistance also play a role 1234.
    - - Speed: The rate at which the runner covers distance (distance divided by time). In the 1500m, maintaining a high average speed is crucial for performance.
      - Velocity: The rate of change of displacement (displacement divided by time), including direction. On a standard track, the direction changes as the runner moves around curves, but the overall velocity is measured from start to finish 1234.
    - - Definition: Momentum is the product of mass and velocity (momentum = mass × velocity). A runner with greater momentum is harder to stop and can maintain speed more effectively.
      - Application: During the 1500m, maintaining momentum is important, especially when accelerating or overtaking other runners 21234.
    - - Definition: Impulse is the change in momentum, calculated as force × time. It relates to how long and how forcefully the runner pushes off the ground with each stride.
      - Application: Efficient runners maximize impulse by applying force over an optimal period, improving acceleration and maintaining speed 14.
- - - - Definition: An object will remain at rest or in uniform motion unless acted upon by an external force.
      - Application: At the start of the triple jump, the athlete is stationary. To begin moving, they must apply a force against the ground to overcome inertia. Once in motion, the athlete will continue moving forward unless forces like friction, air resistance, or the ground during each phase (hop, step, jump) act to change their motion. For example, after take-off, the athlete will continue to move through the air until gravity and ground contact bring them to rest 123.
    - - Definition: The acceleration of an object is directly proportional to the force applied and inversely proportional to its mass (F = m × a).
      - Application: During the run-up and each take-off phase, the athlete applies force to the ground. The greater the force applied (relative to their mass), the greater their acceleration and the further they can propel themselves. For example, a powerful push-off during the hop, step, or jump phases results in greater acceleration and distance covered. The athlete must optimize the force applied in each phase to maximize overall jump distance 123.
    - - Definition: For every action, there is an equal and opposite reaction.
      - Application: When the athlete pushes down and backwards against the ground during take-off, the ground pushes back with an equal and opposite force, propelling the athlete upwards and forwards. This principle is crucial in each phase of the triple jump, as effective use of the reaction force determines the height and distance achieved in each segment of the jump 123.

- - - - Definition: Equilibrium is a state where all forces and torques acting on the body are balanced, so the body is either motionless (static equilibrium) or moving at a constant velocity (dynamic equilibrium).
      - Application in Triple Jump:
        
        During the preparation phase (before the run-up), the athlete is in static equilibrium, standing still and balancing their body.
        
        During the run-up and each phase of the jump (hop, step, and jump), the athlete is in dynamic equilibrium, moving at a constant or changing velocity while trying to maintain control and balance through each movement phase.
        
        Maintaining equilibrium is crucial for smooth transitions between phases and for maximizing distance, as any loss of balance can disrupt technique and reduce performance
    - - Factors Affecting Stability in Triple Jump:
        
        Definition: Stability is the ability of a body to resist changes to its state of equilibrium. High stability means it is harder to disrupt the body's balance.
        
        Base of Support: A wider base (e.g., feet apart during take-off and landing) increases stability. In the triple jump, athletes adjust their foot placement to maintain balance during each landing and take-off.
        
        Centre of Gravity: Lowering the centre of gravity (by bending knees and hips) increases stability, especially during landings. However, during flight phases, the centre of gravity is higher, making balance more challenging.
        
        Line of Gravity: Keeping the line of gravity within the base of support helps maintain stability. In triple jump, athletes must control their body position so their line of gravity stays over their landing foot during each phase.
        
        Mass: A greater mass can increase stability, but in triple jump, athletes balance the need for stability with the need for speed and agility.
        
        Friction: The interaction between the athlete’s shoes and the track surface provides friction, which helps maintain stability during take-off and landing
  - - - Stability is the ability to resist a change in the current state of equilibrium. In running, maintaining stability is crucial for efficient movement and to prevent falls, especially when navigating bends or during changes in pace 1.
      - Key factors affecting a runner’s stability include:
        
        Base of Support: While running, the base of support is narrow (essentially one foot at a time), so runners rely on rapid, coordinated movements to maintain balance 1.
        
        Centre of Gravity: Runners keep their centre of gravity low and slightly forward to maintain forward momentum and stability. Leaning forward helps with propulsion but must be controlled to avoid losing balance 12.
        
        Line of Gravity: The line of gravity should ideally fall within the base of support. In running, this line shifts rapidly as the runner moves from one foot to the other, requiring strong core stability and coordination 12.
        
        Mass: A runner’s mass contributes to their stability. However, excessive mass can make acceleration and deceleration more difficult, so distance runners typically have leaner builds for efficiency 1.
        
        Friction: The interaction between the runner’s shoes and the track surface provides the friction needed for stability and propulsion. Proper footwear enhances grip and reduces the risk of slipping, especially around bends
    - - Equilibrium is a state where there are no unbalanced forces or torques acting on the body. In running, this means the runner is either motionless or moving at a constant velocity (dynamic equilibrium) 1.
        During a 1500m run, athletes are in dynamic equilibrium as they move at a relatively constant speed, especially during the middle stages of the race
