Biomechanics OCR A level PE Questions and Answers with Certified Solutions How does the law of inertia relate to movement in sports? The law of inertia states that an object will remain at rest or in uniform motion unless acted upon by an external force. This means that an athlete’s body or equipment will not change its state of motion without a force applied, such as a push or a pull. What is the role of force in creating movement? Force causes an object to accelerate, decelerate, ...

Kinetic Energy and Jump Height Correct Answer-The relationship between flight height yflight and takeoff velocity vtake-off can be obtained by applying the law of conservation of mechanical energy to the flight phase of the jump. The mechanical energy (E) of the jumper is the sum of the kinetic energy (KE = ½mv2) and gravitational potential energy (PE = mgy). In vertical jumping the effect of air resistance is negligible, and so in the flight phase the jumper can be considered as a projectile i...
