This animation demonstrates the type of engine most commonly used in cars.
This animation demonstrates how an escalator works.
A differential allows the driven wheels of a car to rotate at different speeds when the car is turning.
In transmission systems, the engine torque is modified by reducing or increasing rotational speed.
Some principles of physics can be demonstrated through the functioning of bicycles.
