projectile motion Flashcards
projectile motion definiton
movement of object or human throigh the air
horizontal displacement
shortest distance from the starting point to the finishing point in a line parallel to the ground
what are 3 factors affecting the horizontal displacemnt of a projectile
height of release
speed of release
angle of release
study tip:HAS
angle of release
optimum angle of release is dependent on release hieght and landing height
what is the optimum angle of release when both landing height and release height are equal
optimum angle of release=45 degrees
sport example would be long jump
what is the optimum angle of release when release height is below the landing height
optimum angle of release is greater than 45 degrees
study tip; follow the R
sport exmaple-shooting in basketball
what is the optimum angle of release when the release heighti is greater then the landing height
optimum angle of release=below 45 degrees
sport example=flight path of shot put
speed of release
greater the release velocity of projectile, greater the horizontal displacement travelled
height of release
greater release height, greater the horizontal displacement travelled
what are the two factors that affect flight paths of projectiles
air restaince and weight are two forces that affect projectiles whilst in the air
two factors crucial in deciding whether true parbaloa and distorted parabola
what is a parabola
uniform curve which is symmetrical at its highest point
true parabolic flight path
projectile with a large weight force and small air resistance
example of a true parabolic flight path
shot put
distorted parabola flight path
projectlies with lighter mass effects of air restaince results in flight path devaiting from a true parabola to a distorted parabola
example in sport-badminton a shuttlecock
shuttlecock has light mass and unusual shape which increase its air resiatnce
vector
drawn as arror
shows magnitude and direction
drawing bigger arrow=means more magintute
smaller aroorw=less magnitude
