This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
This unit develops pupils' knowledge of mechanisms through gears and pulleys. By investigating electric vehicles and mechanical and electrical components, pupils will apply their knowledge and understanding by making an electric vehicle.
Lesson Summary
You will learn to create and understand movement with pulleys.
Key Notes
- Listing main components of a simple electrical vehicle starts a design specification.
- Construction kits can be used to explore pulley direction.
- The size of pulleys affects the speed of rotation.
Vocabulary To Learn
- design specification: a list of things a product should have or do
- pulley: a simple mechanism whereby a belt moves around a grooved wheel
- movement: changing place or position
- rotation: moving in a circular motion
- direction: the way something is going or pointing
Common Mistakes To Avoid
- The size of a pulley does not effect the speed of rotation.
3 Quick Questions (With Answers)
1. Explain the lesson in two key points.
Listing main components of a simple electrical vehicle starts a design specification. Construction kits can be used to explore pulley direction.
2. What does this key word mean in this lesson? 'design specification'
a list of things a product should have or do.
3. Correct this common mistake.
Mistake: The size of a pulley does not effect the speed of rotation. Correction: Smaller pulleys rotate faster than larger pulleys on the same system.
