Difference between Speed and Velocity:
-
Speed is a scalar quantity that refers to how fast an object is moving. It is the distance traveled per unit of time, without regard to direction. For example, if you travel 60 kilometers in an hour, your speed is 60 km/h.
-
Velocity is a vector quantity that includes both the speed of an object and the direction in which it is moving. For example, if you travel 60 kilometers to the east in an hour, your velocity is 60 km/h east.
Position vs. Time Graph Analysis:
To determine the appropriate sections where you are walking away from the table, walking towards the table, or standing still, you would typically look at the slopes of the graph:
-
Walking away from the table: This would be indicated by positive slopes on the graph, where the position value is increasing over time.
-
Walking towards the table: This would be represented by negative slopes on the graph, where the position value is decreasing over time.
-
Standing still: This would be represented by horizontal lines on the graph, indicating that the position is not changing over time.
Answering the Journey Analysis
To circle the correct sections (A, B, C, D, E, F, G), you would need to examine the specific elements of your position vs. time graph. Without seeing the actual graph, I can't specify which points correspond to each condition. However, here’s how you can identify:
- Identify positive slopes: Circle those sections as places where you are walking away from the table.
- Identify negative slopes: Circle those sections as places where you are walking towards the table.
- Identify horizontal sections: Circle those sections as places where you are standing still.
Make sure to analyze the graph accordingly to complete your specific sections!
