Final answer:
The x-axis on a position vs. time graph typically represents time, while the y-axis represents position. To find an object's position or determine how long it has been in motion, one can read the graph at the respective time or position. The object's speed or average velocity can be calculated from the slope of the graph, and future positions can be predicted if the speed is constant.
Step-by-step explanation:
Understanding Position, Velocity, and Acceleration from Graphs
To answer the questions about an object's motion given a position vs. time graph, certain quantities are represented on the axes of the graph. Typically, the x-axis represents time, while the y-axis represents the position of the object. Without an accompanying graph, exact numbers cannot be provided, but we can explain the concept.
The position of an object at a specific time can be found by locating the time on the x-axis and reading the corresponding position on the y-axis. The amount of time that has passed when the object is at a certain position is determined by finding that position on the y-axis and looking at the corresponding time on the x-axis.
The rate at which the object travels, which is the speed or average velocity, can be calculated by taking the change in position (Δx) and dividing it by the change in time (Δt). If the object continues at a constant speed, you can predict its future position by multiplying the speed by the desired time.
