Question

The position-time graph of an object is found to be a straight line passing through the origin. What information about the motion of the object is provided by the graph?

Answer 1

You know several things. The graph tells you where the position was at t=0. Second, you know that that since the graph is a line, its slope was constant. The slope of a position time graph is given by:\[m=\frac{ \Delta y }{ \Delta x }=\frac{ position }{ time }\]What is position divided by time?
