projectile motion

Cards (7)

projectile motion  
once a person or object becomes airborne it becomes a projectile.examples:
ball sports (tennis/volleyball)
athletics (javelin/high jump)
vertical component 
vertical– height reached by a projectile effected by gravity
eg. high jump
horizontal component  
the distance covered by a projectile affected by air resistance
eg. long jump
factors affecting projectiles
gravity
air resistance
speed of release
angle of release
height of release
speed of release  
speed at which an object is kicked, thrown, or propelled into the air

the greater the force applied, the greater will be the speed at release and the further the projectile will go
angle of release 
the angle at which an object is projected into the air

optimal AOR when aiming to increase distance (horizontal component) - 45degrees
height of release 
difference between the height that the projectile is released from and the height at which it lands or stops

equal to landing height- 45deg
more than landing height (eg. shotput)- less than 45deg
less than landing height- more than 45deg
