lab question on uniform accelerated motion 7) often a velocity time graph does not pass through the origin. suggest some reasons why this may happen. sure enough my velocity vs. time graph (of average velocities calculated from the slope of tangent lines on the midpoint of a time interval) didnt pass through the origin. so id like to know if im right on this: the reason why a "v vs t" doesnt always pass through the origin is because you cant instantaneously reach a constant acceleration, a cart for example, will have to accelerate un-uniformely until it reaches a constant acceleration. that make sense? thanks in advance.
