[quote=greenice07_iAmTheEnmity]# PHYSICS: You and your classmates went to an amusement park to try the newest rollercoaster ride. The queue for the ride is very long and you were starting to get impatient. Suddenly, the ride controller approached you and told you that he can get you and your classmates a no-queue ticket pass if you could answer his question about the rollercoaster. His question is, “Why is there a need for the rollercoaster car to increase its speed before entering a vertical loop?”[/quote]
maybe because the gravity
pulls the rollercoastercar..
