PROJECTILE+MOTION

When an object is shot in the air from ground level the distance that it reaches will be the same for two different angles of loft. the opposite angle at which it is origonally ,lofted at will shoot the object the same distance as the original angle. for instance if the first shot is fired at 23 degrees then an object shot at 67 degrees will go the same distsance as the object shot at 23 degrees. whne an object is shot from ground level the vertical velocity will decrease according to gravity. once it reaches the peak of the objects flight the vertical velocity will be zero. as it accelerates to the ground it gains its speed and it will have the same velocity as when it was launched. the horizontal velocity is constant through out the entire flight. it never changes becasue there is no forces acting upon it like gravity does for the vertical velocity.

when a object is launched straight out from a cliff the vertical velocity will be originally at 0. once it continues to travel gravity acts and it increases speed according to how far the object falls. the horizontal like the half loop will not change its horizontal velocity.

an object shot up from a cliff will have an original vertical velocity that is not the same as the resultant velocity. the onlt time it will be the same is when the object reaches the level of the cliff again. aas it continues down towards the ground then it will continue to dgain speed resulting in a fsaster speed than what it was origonally launched. again like the first ewxamples the horizontal velocity will stay the same through out the entirty of the flight of the object.
