projectile motion

Question 1

projectile motion

Answer 1

movement of eitherr an object or human travelling through the air

as long as ball released in kick, hit throw becomes a projectile

Question 2

factors that affect horizontal displacement of a projectile

Answer 2

height of release
spped of release
angle of release

HAP

Question 3

angle of release

Answer 3

optimum angle eof release is depednednt on speed and height of release

when both release height and landing height are equal=optimum angle of release is 45 degrees

Question 4

what happenes when release height is below landing height

Answer 4

optimum angle of release needs to be greater then 45 degrees

e.g shooting in basketball

Question 5

if release height is above landing height

Answer 5

optimim angle of release is below 45 degrees

e.g shot put

Question 6

what are the twow forces that affect flight paths

Answer 6

air resistance
weight

decides whether projectile has a flight path that is a true parabola or a distorted parabloa

Question 7

parabola

Answer 7

unforim curve that is symmetrical at its highest point

projectiles with large weight force and small air resitcae have a true parabola flight path

e.g shot put

Question 8

example of distorted parabola

Answer 8

shuttelcock in badminton

lighter mass so the effcts of air resiatnce result in flight path devaiting from trube parabloa to distorted parbaola
