At what point will the roller coaster move the fastest Why?

Cars in roller coasters always move the fastest at the bottoms of hills. This is related to the first concept in that at the bottom of hills all of the potential energy has been converted to kinetic energy, which means more speed.

Formula Rossa is the world's fastest rollercoaster with a speed of 0 to 240 km/h in 4.9 seconds. Feel the surge of 4.8Gs in the pit of your stomach as you scale heart-racing heights of 52m.

Basic mathematical subjects such as calculus help determine the height needed to allow the car to get up the next hill, the maximum speed, and the angles of ascent and descent. These calculations also help make sure that the roller coaster is safe. No doubt about it--math keeps you on track.

In roller coasters, the two forms of energy that are most important are gravitational potential energy and kinetic energy. Gravitational potential energy is the energy that an object has because of its height and is equal to the object's mass multiplied by its height multiplied by the gravitational constant (PE = mgh).

If the tracks slope down, gravity pulls the front of the car toward the ground, so it accelerates. If the tracks tilt up, gravity applies a downward force on the back of the coaster, so it decelerates.

Pretty much any outdoor coaster, especially steel ones will have similar conditions at night. So yes, some attractions do indeed run faster at night, usually due simply to the laws of physics. Additionally, pretty much all attractions also run faster when it is busier do that they can increase capacity.

If the tracks tilt up, gravity applies a downward force on the back of the coaster, so it decelerates. Since an object in motion tends to stay in motion (Newton's first law of motion), the coaster car will maintain a forward velocity even when it is moving up the track, opposite the force of gravity.

Most roller coasters run by the Law of Inertia. Since an object at rest stays at rest, all roller coasters have to be pushed or pulled to get started.

Rollercoaster loops are most often not perfect circles – instead, they are teardrop-like in shape. This is because it takes a greater amount of acceleration to get the train around a perfectly circular loop.
