Question

Select the best answer for the question: Which of the following are examples of coordinate headings?

a. A, i, a
b. ii, 2, B
c. 3, b, iii
d. A, B, C

Answer 1

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.

1. Displacement is the term for the shortest path from start to finish and is a vector quantity.
2. A physical quantity with magnitude and direction is known as a vector.
3. Acceleration is the quantity defined as a change in velocity over a time period.
4. The point from where you take measurements is called the origin.
5. The distance covered in a time interval can be termed as distance or speed depending on context.
6. 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.
