1In the given velocity time graph, of the pieces with uniform acceleration, in which piece does the body's velocity change most rapidly?
2What is a velocity time graph? What goes on which axis?
3What does the slope of a velocity time line show? How is it different from the slope of a displacement time line?
4What does a velocity time line parallel to the x-axis show?
5What does the velocity time graph of a freely falling body look like, and why?
6How is retardation recognised on a velocity time graph?
7An aeroplane starting to take off shows velocities of 0, 2, 6, 12, 20 and 30 m/s. What will its velocity time graph look like, and why?
