followed by close-ups of different gear types, including worm and bevel gears. The film then pieces together a basic motor, labeling and tracking energy flow through its gear system, illustrating ...

Gears can change the direction or the speed of movement. As there are teeth around the edge of the gears they grip together and so can withstand a greater force, enabling them to move large items ...

This video explores different methods that can be use to amplify a force, and focuses on three types of machine - levers, pulleys and gears. The amplification of a force is called mechanical advantage ...

[Steve Mould] shows us a different take – the experimentation kit called Spintronics, which goes the mechanical way, using chains, gears, springs and to simulate the flow of current and the ...
