In the game i am working on, i am launching an object from a specific height (via apply force) with a velocity that changes based on user touch. The object is being launched straight out so there is no angle. I have the equation for finding the trajectory, but i am not sure how i incorporate mass into the equation or if it just figures into the velocity some how. Does anyone know how mass fits in? Here is the trajectory equation that i found:
x = vt cos ?
y = vt sin ? - ½ g t² v is the velocity (in metres per second to agree with the other values below). Now in reality the velocity will slow down due to drag, but that makes it really hard, so let us just say it is the same all the way through!
? is the angle you launch it at
g is the downwards accelaration caused by gravity = 9.81 m/s²
t is time in seconds [import]uid: 26491 topic_id: 30865 reply_id: 330865[/import]
