Yes it is.
The vertical velocity is 0. The horizontal velocity is constant during the entire trajectory (and may be zero).
By the equivalence principles of relativity you do NOThave to choose a stationary point as a reference, Any point in space may be chosen as no point is truly "stationary" and a point that is stationary in one reference frame will be moving in another.
No because enable to see if the object is moving it needs a reference point other than itself.
The trajectory of something is the movement of it when moving through the air. Then you throw a frisbee at a park, it sails across the grass before falling instead of shooting straight up and falling down right away. The trajectory of the frisbee is the path it took before reaching the ground.
Yes it is.

Relative to any chosen reference point.
Trajectory
The vertical velocity is 0. The horizontal velocity is constant during the entire trajectory (and may be zero).
If it is above a chosen reference level (e.g., ground level), it has potential energy. While it is moving, it has kinetic energy.

If you're reading a book in an airplane and it happens to fly over your friend's house,your friend says that the book is moving at 350 miles per hour. But at the same time,you say that the book isn't moving at all, and that's why you're able to read it easily.You and your friend are both correct. In his reference frame, you and the book are bothmoving at 350 miles per hour. In your reference frame, the book isn't moving at all.
What is coding? What could include in a person’s frame of reference? Give examples
It's important to know that you reference point is moving because if an object is in motion and if it changes position it is relevant to a reference point.
