Show transcript
Gears are simple mechanisms or machines which are useful for turning things.
Gears are wheels with teeth that slot together and turn on an axle.
Gears can change the direction of a force. When one gear is turned, the other gear turns in the opposite direction.
Gears of different sizes working together can be used to change the size of a force and reduce the effort required.
A smaller gear will turn rapidly with less force, whereas a larger gear will turn more slowly with a greater force.
