Why is the first hill of a roller coaster always highest?

The first hill of a rollercoaster is not always the highest. But on a typical rollercoaster, the first hill is the tallest because it gives riders a strong dose of excitement. The potential energy stored at the top of the first hill is converted into kinetic energy as the coaster car descends, resulting in a fast and thrilling ride. This sudden release of energy generates a rush of adrenaline and makes riders feel a combination of fear, excitement, and joy. Additionally, the tall first hill serves as a visual attraction for the rollercoaster and often becomes the iconic element associated with the ride.
