Homework Statement
For type 1, 2, or 3 projectiles, which of the following are constant?
Dx, Dy, Vx, Vy
Homework Equations
The Attempt at a Solution
I figure that the only one that is constant in all situations would be Vx because there is no acceleration in the x direction.
Dx would change depending on the height of launch, so would dy, and Vy, would depend on height as well because of gravity. But am I interpreting 'constant' correctly. Vx is the only horizontal straight line in a graph vs time but others are straight just not horizontal.
Basically, what does constant mean in physics in the context of this question?
