1. A particle moved from point A to point B on the x-axis and had a positive displacement. Which one of the following is true? a. particle moved in the positive direction but it is on the negative side of the x-axis b. particle moved in the negative direction but it is on the negative side of the x-axis
c. particle moved in the negative direction but it is on the positive side of the x-axis
1. A particle moved from point A to point B on the x-axis and had a positive displacement. Which one of the following is true?
a. particle moved in the positive direction but it is on the negative side of the x-axis
b. particle moved in the negative direction but it is on the negative side of the x-axis
c. particle moved in the negative direction but it is on the positive side of the x-axis
a is the only possible correct answer with postive displacement.
That's what I figured but I wasn't sure because it talks about the negative side of the x-axis. However, looking at the question again, a) is the only answer that makes sense.
Thank you.
To determine the correct answer, we need to consider the definitions of displacement and the positive/negative directions on the x-axis.
Displacement refers to the overall change in position of an object, taking into account both the distance covered and the direction of movement. In this case, the particle moved from point A to point B, indicating a change in position.
On the x-axis, the positive direction is typically to the right, while the negative direction is usually to the left.
Given that the particle had a positive displacement, this means it moved in the direction of the positive x-axis. Therefore, option a. (the particle moved in the positive direction but it is on the negative side of the x-axis) is the correct answer.
To determine this, you can plot the points A and B on a graph and observe the direction of movement between them. Alternatively, you can also visualize the particle moving along the x-axis in your mind and imagine whether it is moving to the right (positive direction) or to the left (negative direction).
