Projectile Motion Notes Projectile: any object that moves through the air or through space under the influence of gravity
Range: the horizontal distance a projectile travels
Height: the vertical distance a projectile travels
Horizontal velocity: constant, because no force acts horizontally
Vertical velocity: changes, due to force of gravity
Horizontal acceleration: none
Vertical acceleration: acceleration of gravity
For horizontal launches: initial vertical velocity is zero
For angled launches: break up initial velocity into horizontal and vertical pieces
For vertical launches: initial horizontal velocity is zero; object only moves up and down
