Energy in Motion: Exploring Roller Coasters and Scientific Principles

Ms. Sisson introduces energy and its transfer using a roller coaster as an example. She explains potential and kinetic energy, the law of conservation of energy, and different types of kinetic energy. The video also guides students through designing a roller coaster using the scientific method, emphasizing hypothesis creation, experimentation, and data analysis. Additional resources are provided for further learning.

Which of the following is NOT an example of energy?

• It slows down the coaster

• It has no effect on the coaster

According to the law of conservation of energy, what happens to energy?

• It disappears over time

• It changes forms but is never lost

• It is created and destroyed

• It remains constant in one form

What happens to water's potential energy when a dam breaks?

• It remains as potential energy

• It turns into kinetic energy
