Question

explain the conservation of energy in a rollercoaster

Answer 1

The law of conservation of energy states that within a closed system, energy can change form, but it cannot be created or destroyed. In other words, the total amount of energy remains constant. On a roller coaster, energy changes frompotential to kinetic energy and back again many times over the course of a ride.

Answer 2

HERE IS YOUR ANSWER

The law of conservation of energy states that energy can neither be created nor destroyed, but only transformed/converted/transferred to other forms.

The same is applied to a roller coaster project. Gravitational Potential energy on a roller coaster would be the greatest at the highest point of that roller coaster, from where it's launched.Potential energy is defined as:

U= (Mass)(g)(Height)

With mass and gravity staying the same, height would be the factor that would change the potential energy on the roller coaster. The higher the hill, the greater the gravitational potential energy.

As it goes down, the GPE is converted to Kinetic energy, i.e. KE. It then builds up momentum when it goes downhill, and then using that momentum it's able to do lots of crazy stuff like for example the classic loop the loop. The GPE and KE keep alternating in this manner.

Now you may ask why we never talk about momentum when comes to discussing the loop the loop or how the coaster moves.However surprising it may seem, the velocity needed at the bottom of the loop to make it over the top of the loop is totally independent of the mass, so usually we don't discuss roller coaster physics in terms of momentum. We usually do it using velocity equations and we derive them using the concept of energy conservation.
