I have an interesting scenario that a co-worker and I have been arguing over. I noticed that when I accelerate at full throttle to 80km/h then quickly take my foot off the throttle and simutaneously push in the clutch (as to remove the accelerated force) the velocity remains increasing to around 87km/h after a couple seconds where it then begins to decelerate. Why does this occur??? Basic physics dictates that this should not occur. Is there some kind of rotational intertial force of the wheels/ tires/ and drivetrain being greater then the opposing wind resistance forces and the bearing frictional forces??? Or is it something to do with the rate of acceleration change??? All jokes aside I do not own a Prius!! :) This is something I've always wondered. How can the instantaneous velociy remain increasing after letting off the throttle??? Thanks in advance!!!
