why is there a need for the roller coaster car to increase its speed before entering a vertical loop?

    The car needs to be at a critical speed at the top of the loop so that it doesn't fall. The increase in speed is there to compensate for frictional and potential energy losses as it climbs to the top. Technically, the car doesn't need to increase it's speed if it is going fast enough to overcome those losses in the first place. I'm guessing that would be way too fast for us.

    because if it doesnt speed up, the car will get stuck at the bottom of the loop.
