Unit Summary
In this unit pupils will develop core principles knowledge with an explicit focus on exam technique.
Lesson Summary
You will learn to describe the function of gears using specific examples.
Key Notes
- Gears transmit rotary motion.
- A rack and pinion can transfer rotary motion to linear.
Vocabulary To Learn
- gear: a toothed wheel that normally connects to another gear
- driver gear: provides the input movement
- driven gear: provides the output movement
- gear ratio: shows how one gear's speed or force affects another's
- rack and pinion: uses a gear to change rotary motion to linear motion on a rack
Common Mistakes To Avoid
- Increasing the size of the driven gear, increases the output speed.
3 Quick Questions (With Answers)
1. Explain the lesson in two key points.
Gears transmit rotary motion. A rack and pinion can transfer rotary motion to linear.
2. What does this key word mean in this lesson? 'gear'
a toothed wheel that normally connects to another gear.
3. Correct this common mistake.
Mistake: Increasing the size of the driven gear, increases the output speed. Correction: Decreasing the size of the driven gear (or increasing the size of driver gear), increases the speed of the driven gear.
