When the ride reaches the end, the coaster still has energy so it dissipates all of the energy when it hits the brakes at the end allowing it to stop at the station.

Rollercoasters such as the Great Bear have wheels that attach them to the rails on the track. These wheels are lubed and greased to minimize friction when rolling on the track.

The Great Bear's highest drop angle is a 90 degree vertical drop.

The Great Bear roller coaster has never gotten stuck in its lifetime. If it were to get stuck, gravity would pull it down to the end of a drop where the passengers could be guided out of the coaster.

Since the carts are inverted, the carts are connect to the track on a metal rail. The carts have wheels on the rail to allow them to roll around the tracks.

Using the formula for kinetic energy, KE = 1/2 m v^2, the kinetic energy of the coaster can be calculated.
M =  6,300 kg
V = ~25.9 m/s
KE = 2113052 J
The Great Bear has a kinetic energy of about 2113052 J.

While going through the ride, the cart loses some energy when going through loops and corkscrews because of friction and air resistance.

There has only been one minor recorded accident on the Great Bear, relating to a laser being pointed at staff, not resulting in any injury or death.

The train is pulled up 90' by a chain pulley system that is powered by electricity stemming from the ground

At the top of the drop, the passengers have the most gravitational potential energy throughout the entire ride.

When the passengers drop down, the potential energy is converted to kinetic energy and the cart gains speed.

The Great Bear Rollercoaster was first opened under the name Ursa Major, inspired by the constellation Ursa Major,  in May of 1998 in Hersheypark located in Hershey, Pennsylvania.

The rollercoaster had a budget of $13 million and was designed by Werner Stengel and built by Bolliger & Mabillard. It was announced in August 1997.

It was the largest investment the park had ever made for an attraction at the time, and it was the first inverted looping coaster in Pennslyvania.
