The seat is moving downward and is no longer exerting the same upward force on your body. Gravity is pulling you down, but your body is falling at almost the same speed as you would if there was no roller coaster under you. You are nearly in "freefall" until the coaster turns back uphill.
The momentum that you receive from the moving car is almost entirely horizontal, but some fast coasters do impart a slight upward velocity to you if they suddenly turn downward.
Going up and down
A roller coaster increases kinetic energy when it is going downhill, as gravity is pulling it down and accelerating it. The potential energy is converted into kinetic energy as the roller coaster gains speed.
When you are going down you have the most potential energy because the roller coaster and the speed is helping you go faster!
Yes
When the roller coaster starts to stop your body wants to keep moving, that is inertia.
kinda like a roller coaster going up or down
When your body is traveling in a straight line it wants to continue going in a straight line, but the coaster car is not traveling in a straight line and it pulls you down. See related link.

The Demon in Great America, California. (that was my beginner roller coaster)
The limiting frictional force is the force that slows down the tennis ball on the roller coaster.
right when you reach the top and start going down, which is the funnest part!
Potential energy is used when going up hill on a roller coaster. When it starts gong down the potential energy is converted to kinetic energy.
