Final answer:
Coordinate headings like A, B, C are used to organize content hierarchically. In physics, they relate to understanding motion in a coordinate system, describing displacements, vectors, and velocities, and identifying the positive and negative directions along the x and y axes.
Step-by-step explanation:
To answer your question about coordinate headings, options A, B, C are all examples of coordinate headings as they represent a sequence used to organize content in a consistent and hierarchical manner, typically seen in outlines or documents. Now, let's look at the questions you've provided, applying them to the concept of motion in a coordinate system often discussed in physics.
- Displacement is the term for the shortest path from start to finish and is a vector quantity.
- A physical quantity with magnitude and direction is known as a vector.
- Acceleration is the quantity defined as a change in velocity over a time period.
- The point from where you take measurements is called the origin.
- The distance covered in a time interval can be termed as distance or speed depending on context.
- Instantaneous velocity is the term for the velocity at a specific instant in time.
Directional movements in a coordinate system are categorized as follows:
- Moving vertically upward in the coordinate system is along the positive y-axis.
- Moving vertically downward is along the negative y-axis.
- Moving horizontally to the right side is in the positive x direction.
- Moving horizontally to the left side is in the negative x direction.
