Slope Equals Velocity In a position-time graph the velocity of the moving object is represented by the slope or steepness of the graph line. That is we have to find the value of x_1 at time t_1 and x_2 at time t_2. That was pretty clever how you neatly and cleanly cut off the part of the photo that shows the formula were supposed to use.
The position of the object is not changing.
Google Classroom Facebook Twitter. Time graph has a slope of 5 meters1 second for the first five. You can calculate it using this formula total distance total time taken Instantaneous speed. If the graph line is horizontal like the line after time 5 seconds in Graph 2 in the Figure below then the slope is zero and so is the velocity.
