Projectile motion (AQA A-Level Physics): Flashcards

Horizontal and vertical components act independently

$v \sin \theta$ where $v$ is initial velocity

$v \cos \theta$ where $v$ is initial velocity

$0$ m/s

$-9.81$ m/s$^2$ (or $9.81$ m/s$^2$ downwards)

Equal - time to rise = time to fall

Object only affected by gravity, accelerates at $9.81$ m/s$^2$

Constant speed when gravity and air resistance balance

Both decrease

Increases with speed
