When a baseball is tossed directly upward, what is the slope of a plot of its acceleration versus time during the upward flight?
plot has constant positive slope
plot has constant negative slope
plot has zero slope
I think it is zero slope

Physics 
Steve,
no, the acceleration is a constant: 9.8m/s^2 or 32ft/s^2, due to gravity

Physics 
Liz,
If accerlation is constant, then that would show a straight line on the graph, correct? So that line has a slope=0.

Physics 
Fabian,
The plot would have a zero slope. That is the answer.
