Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Energy Law of conservation of energy | Ability to do work Energy can neither be created nor be destroyed but can be transformed from one form to another. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Rubber ball , string | Tie the thread to the ceiling and string the other end to the rubber ball. Grab the ball and make it oscillate and observe energy changes. |
Real life uses :
Energy is used by all in day to day life. When we do work energy is released. The energy is transformed from one form to another thus making it renewable.
Places to visit :
Theme park where a roller coaster is a perfect example.
Practical examples around us
| Examples | Explainations |
|---|---|
| Roller coaster operation | A real example of this law is the roller coaster operation, when you are at the top all the energy you have is potential energy and when you fall the acceleration is because the potential energy is changed into kinetic energy. |
What you learn in Theory:
Energy cannot be created or destroyed.
What you learn in Practice:
Energy transformation occurs between different objects in the universe.
