projectile motion Flashcards
projectile motion
movement of object through air
what are the factors affecting the horizontal displacent of the projectile
angle of release
speed of release
height of release
angle of release
depended on release height and landing height
both landing height and release heigth are equal=optimum angle of release of 45 degrees
e.g long jumper
greater then 45 degrees
this is when the release height is below the landing heigth, then optimum angle of release is greater then 45 degrees
e.g basketballer
below 45 degrees
if release height is above landing heaight, then optimum ange of release is below 45 degrees
e.g shot put
speed of release
greater the release velocity, the greater the horizontal displacement travelled
height of release
greater release height, means greater horizontal displacment
what are the two factors that affect the flight path of the projectile
air restcnace and weight
crucial in decidding whether projectile has flight path of true parabola or distorted parabola
parabola=curve which is symetrrical at highest point
paraboltic flight path
projectiles large weight force samll air resistnace forces follow a true parbolic flight path
e.g shot put
distorted parabola flight path
projectile has lighter mass, resulting in more air restcnace ‘
e.g shuttelcock
