BIOMECHANICS: projectile motion/ parabolic flight paths Flashcards
What is projectile motion?
the movement of either an object or a human body as they travel through the air.
what two forces act on the projectile?
weight and air resistance
what is horizontal displacement?
the shortest distance from the start to finish point in a line parallel to the ground
what three factors determine the horizontal displacement of a projectile?
H: height of release
A: angle of release
S: speed of release
why does the height of release determine the horizontal displacement?
a greater release height results in a increased horizontal displacement.
why does the angle of release determine the horizontal displacement?
optimum angle of release is 45 degrees or maybe different depending on the height of realase.
why does the speed of release determine the horizontal displacement?
the greater the release of velocity of projectile motion the greater the horizontal displacement travelled.
why would the optimum angle of release or take off be 45 degrees?
as the release point is at the same level as the landing point.
why would the optimum angle of release or take off be 50-55 degrees?
as the landing point is higher than the release point.
why would the optimum angle of release or take off be 38 degrees?
as the release point is higher than the landing point.
what is a parabola?
a uniform curve that is symmetrical at its highest point.
examples of a parabolic flight path?
a shot put
examples of a non-parabolic flight path?
a badminton shuttle
