A projectile is any object that is cast, fired, flung, heaved, hurled, pitched, tossed, or thrown. (This is an informal definition.) The path of a projectile is called its trajectory. Some examples of projectiles include …
- a baseball that has been pitched, batted, or thrown
- a bullet the instant it exits the barrel of a gun or rifle
- a bus driven off an uncompleted bridge
- a moving airplane in the air with its engines and wings disabled
- a runner in mid stride (since they momentarily lose contact with the ground)
- the space shuttle or any other spacecraft after main engine cut off (MECO)
What force controls the flight ?
What force is in play the whole way through the flight ?
What direction does this force act ?
H/W Draw a diagram of the flight path of an object, at 4 various angles !

Time of Flight = t @ Sy = 0
Range = Sx @ ToF
not really projectiles, similiar & interesting
