This image contains a position-time graph along with related questions in Persian. Here's the breakdown of the questions and an explanation of how to address them based on the graph provided:

1. Question (الف):
   "مسافت طی شده در ۴ ثانیه اول حرکت چند متر است؟"
   Translation:
   "What is the distance traveled during the first 4 seconds of motion?"

   Solution:

   • To calculate the total distance, observe the absolute value of the graph in the first 4 seconds. Sum the lengths of all segments regardless of direction.

2. Question (ب):
   "در چه لحظاتی متحرک تغییر جهت داده است؟"
   Translation:
   "At which moments does the object change direction?"

   Solution:

   • The object changes direction at points where the slope of the graph changes sign (crosses the x-axis).

3. Question (پ):
   "در لحظاتی که متحرک در خلاف جهت محور حرکت کرده است مسافت طی شده چند متر بوده است؟"
   Translation:
   "During the moments when the object moves in the opposite direction of the axis, how much distance is traveled?"

   Solution:

   • Identify the intervals where the graph is below the x-axis (negative position). Calculate the total absolute distance traveled in these intervals.

4. Question (ت):
   "در چه لحظاتی مکان متحرک تغییر جهت داده است؟"
   Translation:
   "At which moments does the position of the object change direction?"

   Solution:

   • Similar to question (ب), the moments of change in direction are when the graph crosses the x-axis.

Related Questions:

1. How do you calculate the total displacement during the first 4 seconds?
2. How can you determine the velocity at any given time from the graph?
3. What is the difference between displacement and distance in motion graphs?
4. Can this type of graph represent acceleration, or is it only for position?
5. How do we distinguish between instantaneous velocity and average velocity using such a graph?

Tip:

To solve motion-related problems effectively, always distinguish between scalar (distance) and vector (displacement) quantities.
