What are the forces that act upon amusement park rides? Why is it important for engineers to understand how motion and forces affect the rides they design?

In positive numbers less than 1, the zeros between the decimal point and non zero are significant

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

Students design a model roller-coaster track. they place a rubber ball at the highest point on the track and let it go. the ball rolls along the track pulled only by the force of gravity. eventually, it comes to a stop. which change to the design will result in the ball moving the greatest distance?
