is moving backwards at the same speed. If the slope is consistently zero, the object has completely stopped moving for a span of time. 5. When the slope of a distance vs. time graph is changing, the speed is changing. If the slope of a line is increasing in either the positive or negative direction the object is accelerating and if it is decreasing the object is decelerating. If the slope changes from positive to negative, the object is changing direction. Velocity vs. Time 7. Part D: When matching this graph, we stood still for 2 seconds before taking quick step backwards and keeping a constant pace in that direction for 3 seconds. Then we needed to stop moving for 2 seconds before stepping forwards and keeping the same consistent pace as before until the time limit is complete. Part E: When matching this graph, we begin by immediately accelerating backward for 4 seconds up to 0.5 m/s and then maintaining that velocity for 2 seconds. Then we took a step

When the slope of a velocity vs. time graph is zero, the object’s speed is constant. This can be either in the positive of negative direction, or it could be standing still.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
