What keeps rollercoasters at a continuous speed throughout the ride so that it’s able to complete twists, turns and loops?
In: Engineering
Rollercoasters actually don’t keep a consistent speed. They get towed up to the top of the first hill, then that potential gravitational energy is all the energy they will ever have. From there, the car is simply rolling down the hills. They have enough energy to roll up another smaller hill then back down again, but that’s just left over momentum from the first drop. Nothing ever adds energy after the first towing up the first hill. It’s all just controlled falling
