I've gotten the slope on a force vs. acceleration graph ( force on the vertical, acceleration on the horizontal) and the slope is 1372 units (whatever the units are) I've found out that the slope is supposed to represent the amount that acceleration increases for a unit increase in force but that doesnt makes sense....the acceleration increases by 1372 units for every unit of increase in force? please help
You seem to have it backwards. Remember what slope is: Δy/Δx, or in your case ΔF/Δa. It is the force that changes by 1372 units for a unit increase in acceleration. By the way, what units do you get when you divide a force by an acceleration?
