The graph shows the time versus distance data gathered for four different balls in laboratory 022.
The first four questions are matching. Use the letters A, B, C, and D at the end of the lines on the xy scattergraph.
_____ Ball not moving: stationary.
_____ Ball slowing down.
_____ Ball moving at a constant non-zero speed.
_____ Ball speeding up.
___________________ Determine the speed of ball D.
___________________ Determine the speed of ball A.
___________________ Determine the speed of ball B between 4 and 5 seconds.
___________________ Determine the speed of ball C between 7 and 10 seconds.
A rolling ball cannot generate a vertical line on a time versus distance graph. Why?
