The highest point of a roller coaster is almost always the first hill. In the majority of roller coasters, the hills get smaller as the train travels down the track.
To find the answer, we have to know more about the mechanical energy of a system.
How to find the answer?
- Since it influences the mechanical energy of the system, the first hill must be the highest.
- One of the fundamental tenets of physics is that, in the absence of friction, mechanical energy must be conserved. Mechanical energy is the product of kinetic energy and potential energy.
- When the vehicles ascend the first hill on the roller coaster, mechanical energy is provided to the system because the speed is zero at this point.
Mechanical energy = U = mgh
Where m represents the car mass, g represents gravity, and h represents height
- If the system is to continue moving, the other hills on the mountain must be lower than the first hill. When the vehicles are released, this energy is converted into kinetic and potential energy when it lowers and ascends, but the sum of these two cannot be larger than the starting energy.
Finally, by applying the principle of energy conservation, we may determine that, the initial hill must be the highest.
