Short Answer Key

1. Kinematics is the study of motion without considering the forces that cause it. In the standing broad jump, kinematics helps us analyze the jumper's position, velocity, and acceleration during the jump.
2. Velocity is the rate of change of displacement, having both magnitude and direction. Acceleration is the rate of change of velocity. They differ in that velocity describes how quickly an object changes position, while acceleration describes how quickly velocity changes.
3. Force is crucial in a standing broad jump as it is needed to propel the jumper off the ground. The jumper exerts a force on the ground, and the ground exerts an equal and opposite force back, launching the jumper into the air.
4. The impulse-momentum theorem states that the change in momentum of an object is equal to the impulse applied to it. In a standing broad jump, the impulse from the ground on the jumper changes their momentum, leading to their takeoff velocity.
5. The law of conservation of energy states that energy cannot be created or destroyed, only transformed. In the standing broad jump, the jumper's potential energy is converted into kinetic energy during the jump, and back into potential energy as they land.
6. Factors influencing jump distance include the jumper's leg strength and power, technique (takeoff angle and body position), body mass, air resistance, and the surface they are jumping from.
7. The angle of takeoff significantly impacts jump distance. The optimal angle for maximum distance is typically around 45 degrees.
8. Air resistance opposes the motion of the jumper, reducing their horizontal velocity and limiting jump distance. While its effect may be small for a standing broad jump, it's still a factor to consider.
9. Tracker allows researchers to track the jumper's motion frame by frame, measuring position, velocity, and acceleration over time. This data helps analyze the jump technique and identify areas for improvement.
10. The physics principles involved in a standing broad jump have applications in sports, biomechanics, engineering (designing jumping robots), and understanding human movement.
