Overview

Read the introduction, objectives and theoretical background to the project and then answer the following questions:

• What main theory or concept is the project based on?

For The Fastest ball challenge, it revolves around one of Newton's laws, For example, the solution for the impact velocity of a falling object is much easier by energy methods.

For the Caffeine extraction, it is based on the solubility of caffeine and other materials in tea to make the experiment work. It also involves on how the molecules in tea work.

• What do you already know about this theory or concept?

We know that for Newton's law for the fastest ball challenge, the larger the angle, the more potential energy the ball bearing has, and thus have more kinetic energy.

For the Caffeine extraction, we know that caffeine is used in many drinks, and it can be good or harmful.
