velocity time Click here to open the simulator: https: //ophysics. com/k 5. html Your screen should look like this (1) Drag the blue, green and red dots to make the position, velocity and acceleration all zero like this: (2) Increase the velocity by dragging the green dot. Use the sim to neatly sketch the position vs time graphs for the three different velocities show: (3) Briefly describe how the position graphs in (A), (B) and (C) look different from one another and why they are different. (A) (B) (4) Suppose the velocity was made negative like this: Without drawing anything, describe what the position vs. time graph would look like in the space below. Use the sim if you need help (C)

(5) Next make the acceleration constant and positive like this: Make sure initial velocity=0 and initial position=0. Sketch the graphs: Large slope (6) What is the relationship between the shape of the velocity and acceleration graphs? We can explain the velocity graph from the position graph for accelerated motion by inspecting tiny line segments along the curve. The slope of each tiny line segment is increasing as time goes by and since the slope of the position graph is the velocity, the velocity is therefore increasing with time. See here all m S pe slo (7) Look at the position vs. time graph shown on the right. Three line segments are circled and labeled (a), (b) and (c). Place a check mark in the appropriate box in the table below. Line segment Slope is positive Slope is negative Slope is zero (b) (a) (b) (c) (a) (c) (8) Suppose the graph in (7) above was representing the motion of a car moving along a straight line. In your own words, give a complete description of this motion over the entire time interval.
