Ben Castiglia's Roller Coaster Padlet by Ben Castiglia's https://padlet.com/Benc/Bencastiglia en-us 2014-04-07 16:20:50 UTC 2025-09-24 04:18:40 UTC hello@padlet.com http://d262le4z25sx36.cloudfront.net/portraits/monkey.jpg Acceleration Benc https://padlet.com/Benc/Bencastiglia/wish/25554249 If an object changes its speed or direction, it is accelerating. Roller coasters change acceleration a lot because they go in all different directions and speeds. Roller coasters have large accelerations, but a ride like the tea cups would have a small acceleration.

In a loop on a roller coaster, riders are pushed toward the tracks.

It is equal to the acceleration that gravity has caused. Free falling objects on earth change at a rate of 10m/s. So, an object that is at 4 g's of acceleration, it changes at a rate of 40 m/s a second.

Anything that is in motion has momentum. If the object has a lot mass, then it will have more momentum than something with less mass if they are going at the same speed. So, if a roller coaster and a ping pong ball are going at the same speed, then the roller coaster will have more momentum.

Lets say the rider weighs 120 lbs; they would feel the 120 lbs. of force from the seat pushing against them, but they would feel normal. When the ride starts, the seat drops out from under you and you feel weightless.

Friction happens when there is a close interaction between two things that are sliding across each other. When a roller coaster comes to a stop, it is because of friction.

When the object is in motion is has kinetic energy. When the roller coaster goes up, the higher it goes up, the more potential energy it has. then, when the coaster falls, the potential energy is turned into kinetic energy.

PE = mh x (9.8 m/s/s

Potential Energy is measured in joules

KE = 1/2mv^2

Kinetic Energy is measured in joules

When you go down the hill, there is more kinetic energy.

Some people believe that the French invented the roller coaster. In the 1850's, a mining company in Pennsylvania used an 8.7 mile track to transport coal. Later they started charging people for rides at 50 cents a piece. In 1959 Disneyland introduced steel tracks, which allowed roller coasters to be built in any way possible.

The fastest steel roller coaster is Formula Rossa, with a top speed of 148 mph. The steel roller coaster with the longest drop is Kingda ka with a 418 ft. drop.
