Projectile Motion
Projectile motion is the vector sum of both horizontal motion and vertical motion.
The shape of projectile motion looks like a parabola.
Horizontally:
The speed of an object is constant because there is no force to either speed it up or slow it down. It travels equal distances in equal intervals of time.
distance horizontally = constant velocity X time or d = v·t
Vertically:
The speed of an object is under the influence of gravity.
Gravity is equal to 9.8 m/s which we round off to 10 m/s.
This is cause the object to speed up by 10 m/s every second it is in the air.
The distance it travels increases every second it is in the air.
Distance vertically = ½ gravity X time squared or d = ½ gt
If we use the rounded off value of “g” then d = 5 t.
The time to fall vertically is the same, if it fall down vertically, or if it is shot out at a constant speed.
If you know the height from which an object is dropped, you can calculate the time to fall to the ground by using the formula: t = or t =
If a picture is drawn of it position with a constant horizontal speed and an increasing vertical speed it would look like:
↓→ o o o o o o o o o o
