In summary, the normal force on the top of a roller coaster is greater than the force of gravity because at that point, the track is pushing the coaster down. If the normal force was less, the coaster would fly off the track. This is different from being at the top of a hill where the track is below the coaster and if going fast enough, the normal force may be less and the coaster could potentially fly off as a projectile.

You mean at the top of a loop? Because if it's at the top of a hill it isn't.

Are you talking about the coaster on the inside of a loop at the top where the track would be pushing it down or the coaster being at the top of a hill where the track would be below the coaster?

If you were in a loop, and the force of gravity was greater than the normal force, you'd fall out of the ride.
If however you were going over the hill where the track was below you, the normal force would be less and if you were going fast enough, gravity wouldn't be enough to keep you on the track and you would fly off as a projectile.

Yes that's exactly what i was finding for.thanks br
1. What are the main forces acting on a rollercoaster?
The main forces acting on a rollercoaster are gravity, normal force, friction, and air resistance. These forces work together to keep the rollercoaster on its track and provide the thrill and excitement of the ride.
2. How does gravity affect a rollercoaster?
Gravity is the force that pulls objects towards the center of the Earth. In the case of a rollercoaster, gravity is responsible for pulling the train down the track and creating the sensation of weightlessness during drops. It is also the force that allows the rollercoaster to complete its loops and inversions.
3. What is the role of normal force in a rollercoaster?
The normal force is the force exerted by a surface on an object in contact with it. In a rollercoaster, the normal force is what keeps the train on the track and prevents it from flying off during turns and inversions. It is essential for the safety of the riders and the overall functioning of the rollercoaster.
4. How does friction impact a rollercoaster ride?
Friction is the force that opposes motion between two surfaces in contact. In a rollercoaster, friction is responsible for slowing down the train and controlling its speed. Too much friction can result in a less thrilling ride, while too little friction can make the ride unsafe and uncontrollable.
5. What role does air resistance play in a rollercoaster ride?
Air resistance is the force that opposes the motion of objects through the air. In a rollercoaster, air resistance can affect the speed and smoothness of the ride. It is particularly important for high-speed rollercoasters, as it can impact the train's ability to complete certain elements of the track, such as loops and twists.
