projectile motion

• refers to movement of either an object or a human body as they travel through the air
• factors affecting projectiles include angle of release, speed of release and height of release
• angle of release is dependent on the release height and landing height

  when landing and release height are equal optimum is 45 degrees - long jumper
• if landing height is above release height then the optimum baffle is greater than 45 degrees - shooting in basketball
• if landing height is below angle of release, angle of release should be less than 45 degrees - shotput
• speed of release 


  the greater the release velocity of a projectile the greater the horizontal displacement travelled
• height of release


  the greater the height also results in an increase in horizontal displacement. force of gravity constantly acting on a mass this means that an athlete should aim for the highest point possible above the ground to gain the furthest distnac
