Ephe 341 - Study guides, Class notes & Summaries

The study of motion of an object about a circular path exclusive of the influences of mass and force - What is Angular Kinematics? Angular displacement, angular velocity, angular acceleration. - What does Angular kinematics include? Occurs when all points on an object move in a circular path around the same axis - When does angular motion occur? The angle an object moves through from its starting position relative to an axis of rotation - What is angular displacement defined as? Theta ...

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...
