Unit Summary
This unit focuses on quantifying and comparing energy transfers in different processes, such as motion changes, electrical circuits, and fuel burning. It examines forces as interactions between objects, using diagrams and measurements, including contact and non-contact forces.
Lesson Summary
You will learn to identify when stores of energy change, and describe causes of energy transfer between stores.
Key Notes
- Energy cannot be created or destroyed.
- Energy can be transferred by forces that change the properties of an object (or system).
Vocabulary To Learn
- store of energy: A store of energy describes the different ways in which energy can be stored.
- surroundings: An object's surroundings include everything that is around it.
- energy transfer: An energy transfer takes place when the amount of energy in some stores decreases and increases in others.
Common Mistakes To Avoid
- Energy can be used up.
3 Quick Questions (With Answers)
1. Explain the scientific idea in this lesson using two key points.
Energy cannot be created or destroyed. Energy can be transferred by forces that change the properties of an object (or system).
2. Define this scientific word and use it in context. 'store of energy'
A store of energy describes the different ways in which energy can be stored. Include the word in a full scientific explanation, not as a single label.
3. Correct this common scientific misunderstanding.
Mistake: Energy can be used up. Correction: Describe the mechanisms that transfer energy from one object to another, or to a system, as the energy in the original object decreases – or vice versa.
