Yes it is.
Stationary reference points are chosen to determine motion because they provide a consistent and fixed frame of reference. By using stationary reference points, it is easier to identify when an object is moving relative to its surroundings. This helps in accurately measuring the speed and direction of the object's motion.
The curved path of an object moving through the air is called a parabolic trajectory. This trajectory is a result of the combination of the object's initial velocity and the force of gravity acting on it.
direction
No, movement can be measured in relation to any reference point, whether fixed in pace or not. Measurements often involve comparing the position of an object or system to a chosen reference point, allowing for the quantitative analysis of its motion. The reference point itself does not necessarily have to be fixed in pace for this comparison to be made.

If it is above a chosen reference level (e.g., ground level), it has potential energy. While it is moving, it has kinetic energy.

Yes, a position-time graph can have a negative slope. This would indicate that the object is moving in the negative direction with respect to the chosen reference point.

The path taken by a moving object is called its trajectory. It describes the route or journey followed by the object as it moves.
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.
