assumed to be constant
-depends on horizontal component and time
also known as 2 dimensional motion
An object that is thrown has a(n) _____ horizontal velocity that is equal to ____
In both cases, there is no horizontal force acting on the projectile after it is released, so there is no horizontal ____
Both a thrown object and a dropped object are accelerated downward by the _____
force of gravity
The amount of acceleration of the thrown object is ____ the amount of acceleration of the dropped object.
A projectile launched from a moving source will have different trajectories when seen by observers with different ____
points of view
An observer moving with the source of the projectile will see the trajectory as having no _______ component.
However, an observer not moving with the source of the projectile will see the trajectory as having both a(n) ______ and _____ component
If a projectile is launched horizontally, its initial horizontal velocity may vary, but the initial vertical velocity is ____.
As the projectile follows its trajectory, its vertical velocity _____ while its horizontal velocity _____
increases, stays the same
