My Question: Does it take science to make a marble run work?

Introduction

Hello my name is Lasa, and I am going to explaining what a marble run works. I’ll be taking you into some “scientific things”. I wonder what makes a marble move down lets go it gravity.

How gravity works

The answer is easy but again “scientifically important”. The magic is Earth moving round the Sun is in a dynamic equilibrium. The speed of the Earth's movement creates a centrifugal force which balances the gravitational force between the Sun and the Earth. ... Because there is no force to stop it.  

Kinetic energy, accelerate, decelerate

The power of movement is due to kinetic energy. The marble is accelerated faster and faster as it is using kinetic energy. When the marble slows down that is called anti acceleration.

Conclusion

In conclusion it actually does take science to create this wonderful creation.
