Study Guides
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 adapt a design to make it more effective.
Key Notes
- The body of a vehicle is the outer shell which sits on the chassis.
- Aerodynamics reduce drag and fuel consumption.
- Car designers test and consider the chassis and body for best performance.
- A car body design needs to be shaped to consider aerodynamics.
Vocabulary To Learn
- aerodynamics: the way air moves around an object
- body: the main structure of a vehicle built on to a chassis
- performance: how well something works
- drag: air pushing against a moving object
Common Mistakes To Avoid
- The shape of a vehicle has no effect on its speed.
3 Quick Questions (With Answers)
1. Explain the lesson in two key points.
The body of a vehicle is the outer shell which sits on the chassis. Aerodynamics reduce drag and fuel consumption.
2. What does this key word mean in this lesson? 'aerodynamics'
the way air moves around an object.
3. Correct this common mistake.
Mistake: The shape of a vehicle has no effect on its speed. Correction: Vehicle shape is considered in order to reduce air resistance (less drag).
